DCET 2026 QP KEY ANSWERS |VERSION B1 |ND Academy Live #ndacademy #dcet

0:00 Hello Namaskara Welcome back Welcome to Navdeep Ram channe So dear students you are waiting from now I think everyone did the exam well So I think exam paper was easy But I asked more about application level and math following I have told you this many times You can ask about patterns Last time I asked about assertion and analogy and math following I asked more about math following and analogy I asked one question I have given you 4

0:45 questions I have given you 4 questions A1, B1, C1, D1 and I am giving B1. So you have got 4 questions. So in B1, IT skills are 1 to 10 and 90 to 100. I have shown you that I am shuffling. If you start, you will get it till the end. page adjustment and diagram adjustment is done to adjust the page, because the page is set for that page so IT skills are 1 to 10 and 91 to 100 FEEE is 11 to 30, this is B version, as I said for B version PMS is 31 to 50, MATS is 51 to 70 and SNDI is 71 to 90 remaining version will be uploaded shortly, wait in the group, ok I will do the video in all the versions So now, first let's see

1:34 the IT skills 1 to 10. So question number 1 is here. Option 3 is here. So you can see here it's option 3. Option 3 is the answer to question number 1. Question number 2 is here. Option 1. Question number 3 is here. Option 4. Question number 4 is here. Option 4. Question number 5 is here. Option 2. Question number 6 is here. Option 2. Question number 7 is here. Option 2. Question number 8 is option 3 Question number 9 is option 3 Question number 10 is option 4 So, all these IT skills are 1 to 10 Next is FEEE FEEE is easy to understand but it is not that easy to understand math and following I have told you many times that it is easy to understand math and

2:20 following So, I think if you have followed it is easy, there is no tricky question The material used for firing is option 4, Nitrogen. Question 12 is Galvanized Iron. It is option 4. Question 13 is which of the following is conventional source of electrical energy? Thermal energy. This is non-conventional. It is recyclable. It is non-recyclable. as i told you option 2 is coming, so option 2 is coming here, only A and B, because current has amperes and emf has volts, electrical energy has ampere per hour, kilo watt hour, resistance has ohms and moles, so these two are wrong, so option 2 only Next, you will get option 1, which is A1, B1, C4, D3. To match these following, check option

3:11 1. Ammeter for current, voltmeter for potential difference, wattmeter for power and ohmmeter for resistance. So, next to solve the value of current, we need to check the answer of 1 and 2 amps. We need to apply the formula of Vr=Vr=Ir in the ohms formula. For parallel connection, we need to use 1/Rp=1/R1+1/R2. next is same, we have to take I first, voltage across this one, if you think this is V, first take I, if you want I, you have to take RT, RT=RS+RP, if you count the same, the answer will

3:56 be 3V, voltage across 3 ohms is 3V, check it, I will solve it So, the function of a fuse wire is option 3. The protection circuit is not under voltage or over voltage. Next option is rating of a fuse wire. The maximum current at which the maximum fuse burns. Mat da following keldi dhani matta option 2 barathe so glass cartridge fuse bandhu electronic equipments barathe idhu idhukke kit kat fuse bandhu residential wiring barathe HRC fuse bandhu power distribution samayal barathe fuse wire bandhu emergency production karathe nimge so D bandhu 1

4:43 agathe so it is option 1 similarly n1 also ok so what we are asking here is number of turns 1, number of n1 represents the primary turn and n2 represents the secondary winding so when it is primary and secondary so option 1 is given here so what we are asking here is only one winding N1 is equal to N2 is isolation and N1 less than N2 is step up because primary is less and secondary is more so this is the step down so for this step down will come because N1 is more and N2 is less so option 1 will come next properties of ideal transformer is no winding resistance so for this high winding resistance will

5:31 not be there so for that option 1 will come for ABC and D will not be there so option 1 will come identify the properties of ideal transformer ideal transformer will be no winding resistance, no leakage plus, no iron losses will not be there so option 1 will come Next option is N2/N1=V2/V1, if you apply this formula you will get 5 turns across secondary N1=5 turns across secondary N1=5 turns across secondary Next is the capacity of

6:18 a battery primarily measured in ampere hours. Next 26th is the answer of XOR gate. Next, when the correct answer comes, option 2 comes. B and C are correct. So, what are the sensors used for? To measure. It is an input device for measuring. Not for controlling, not for generating. PLC is program logic controller option 2. How many direct questions are there? Input AC output pulsating AC is nothing but rectifier option 2. Next one is CPU RAM and ROM micro controls option 4. How many FEEE? Next is FEEE, PMS 31

7:08 to 50, PMS 31 to 50 is the analog type, Option 1 for 31, Option 3 for 32, Option 1 for 33 34 is option 2, rework 35 is option 1 36 is option 4 37 is option 3, project manager 38 is option 3, check these options 39 is option 1, uncertainty For 40th it is option 2, critical. All direct questions are not like this. Only few have been

7:58 asked about the application. Where there is more units, programming concept, Python also asked. So for question number 41, option 2 will come. For question number 42, option 3 will come. So choose this. In 43, it is option 3, both 1 and 2 are available. You are asking direct questions, not so hectic. In 44, it is option 2, network technique. All these are available in B1. In 45, option 1 is available, this option is available. Next to 46, you will get option 3. So option 3 is available here. In 47, it is option 3, post audit is available. For 48, you will get option 2. For 49, you will get

8:43 option 1. For 49, you will get option 2. For 50, you will get option 2. Next is very easy Maths. I have asked all the direct questions. I think I have not seen this much easy. Square matrix is diagonal. It is option 3. Option 3 is the value of sin x into cos x is determined 3 into 3. When sin square x plus cos square x is solved, option 3 is obtained. Next, in square matrix, we have done revision of the previous question. We have given a into adjoint a and determined a into i. We have asked the same question in reverse. We have asked this in 25 and this is the same. Option 1 is the same. Minors are option 2, -42, -19, check it out. Which is

9:31 the minor? So, 5 is 2, right? So, when you do this, you have to keep this, and when you do this, you have to keep this. Check it out, determine it, and you will get the answer. So, next is 55. It is x plus y plus lambda, right? So, nothing, x, y, substitute it, and give a point. Lambda is option 3, -3, right? 1 plus 2 is equal to 3, right? If you look there, it is -3, right? So, 4x, right? Slope is, slope is, minus a by b, so m is equal to minus a by b, that is equal to minus 4 by minus 3, it is nothing but cancel, 4 by 3 will come, it is option a, so I have asked it simply, parallel to y axis, nothing but infinity, because when we give slope, parallel to y axis, So, angle 90,

10:19 so theta is equal to 90. So, tan 90 is equal to infinity. Tan 0 is equal to 0. So, it is option 2. So, how easy is it? inclination 135 degree theta = 135 find out m = 1 substitute and get the answer option 2 ok you can link it y intercept m = 4 y = mx + c you will get this answer ok same equation and to solve this product rule 2x1/x you will get 2 solve it and 2/2 Next to derivative of e to the power of x. Product rule is there. If

11:04 you do product rule, you will get this one. e to the power of x is equal to minus sine x into cos x. You know this. So, e to the power of x, 3x is d square by dx square. Composite is successive. So, it is option 2. So, it is option 2. So, it is option 2. So, it is option 2. So, it is option 1. Next, we have integration e^x to e^x, log x to 1/x, sec^x to tan x. So, option 3 is coming. This is in B1. Put sin x = t = integration of t to the power of 6 and t to the power of 7 by 7. So the answer is option 3, that

11:54 is sin to the power of 7x by 7. Because t is sin x. Simple. Next is integral of x cos x. So, directly from the tabular method, so differentiation, integration. So, integration, you will get the value of x sin x plus cos x. Or you can use the integration by parts, Eylet formula. Eylet formula can be used by integration by parts, integration of uv. So, answer is 2. 66 is option 1, so when we generate it, integration is pi*y^2 a^b, so when we cancel it and solve it, we will get this one, limits. Next, the value of sin 480.

12:41 I have asked for the allied angles. 480 minus 360, that is equal to 120. So, sin 120 is equal to 180 minus 60. So, finally, sin 60 is equal to root 3 by 2. So, the answer is option 1. So, next, sin of A plus B formula. I have asked for the formula. Sin A cos B plus cos A sin B. We all know this. Satya and Kalki. okay so plus is option two Next cos A sin B, as we have heard in Pythagoras, 12, 13, 5, 3, 4, 3, 5, 4 will come. So, calculate all these and take sin A, take A, take B, take A, take B, A, 13, cos 12 will come here, here 5

13:29 will come, B here sin B, here 5, here 3, here 4 will come. So, similarly find out you can substitute sinA and cosB and apply the same formula for the answer you will get the answer 63/65 same thing, how many concepts are used to explain the tricks the value of sin 125 sin 15. See, instead of applying this in an off-angle form, we need to write 180 minus 55. sin of 180 minus 55. So, 180 minus second quadrant according to the ASTC rule. so this is sin55 and sin^2 = sin55*sin55

14:19 and sin^2 = sin55 and sin of 90-55 and cos35^2 and that is the answer option to cos square 35 so if you connect it like this, I have asked a little more application level, but the concept is easy if transformation is not done, you can do like this, when you do allied angle series, very easy to understand, so how much mass is said, I have not seen how easy it is, so I asked it so easily, then 71 to 90 will be SND, 71 will come to option 2, I have no idea about SND, I will cancel it, then option 3, 72 will come to option 3, check it, 73 will come to option 3, from 2020 to 2023, 74 is

15:08 option 2 from 2021 to 2023 75 is option 4 with answer 17 76 is option 1 with direct question formula 77 is option 2 with answer 0 78 asked for option 1, so it means A and B are correct. I have also told you that statements are correct and incorrect. I have also done a video on correct and incorrect. So 79 again asked for direct questions. Option D comes. Then 80 comes and option 3 comes. It asks for math the following. Math the following is asked for concepts. For small concepts. Next, 81

15:54 asks for Python. so option 2 is loops, python package library, science and numeric has no loops, it has numpy, matlab and pandas if you miss it, you have to check the marks and it is there Next is 82, to identify indentation, define the block of code. So option 2 is done. When it comes to loop inside the loop, usually people come up with inside loop, but this is not the answer. The answer is nested for loop. Because for loop is not used in Python. Actually it is a tricky question. So the output is option 3, option 3 is 1. Because A double star and the red a double star three and the rate of the power of three and the so a one do five to the power

16:42 of three that is equal to 125 or a step so in care of the n is called 125 plus B and ray a to that is equal to 133 but at the Emily n mod 2 and the red 133 mod 2 and the divide Agatha so 133 divided by 2 and the red divide one of the remainder bundle one bar at the remainder bundle 132 under a 6x12 = 132, so remainder is 1, so answer is 1. When I do modulus, I will get the answer as remainder. So, this is a little confusing. This is quotient. When we divide, quotient is obtained. When we do modulus, remainder is obtained. so the answer is option 3 so next we have

17:29 to do the following, this is the complex number this is the floating point, this is the string and this is the integer so option 3 is this, so we will do one by one and it will be easy for you to do this output of the given program is option 1, b because x value is 0, x is equal to 1 means true true means it will come here, so false means it will come here, so it is true True or false will be displayed here. So option 1 will be displayed here. Next is 88, fastest collection of data is option 3, the survey. See how easy it is to ask direct questions. Next

18:19 is the last question of S&A, option 2. Next is 91-100, IT skills. IT skills is remaining part. From remaining 11th, I have heard a C program. Option 2 is 135. Here, I have heard A++. A++ means post increment. It is a little bit depth. this is a tricky question, so a++ is post increment, value is assigned and then increment is done so here 10+a++ is first this part is executed value is assigned and then increment is done, what happens when a++ is done? a++ is something but 125, what is the value? so

19:04 a value is 125, so a++ is 126, when assigned, not assigned here so 10+125 becomes 135 and that is the answer option So, it is a bit more depth, so you can't do any trick question. Which of the following is valid and different? You can't start with a number, slash, symbol, number. So, this is option 4. Next option 2 is for MACDOP following. Next option 4 is for communication. Next option 2 is for 95. Next option 3 is for web browser. Next option 2 is for 98.

19:50 I asked for the order, so option 2 is coming in 99, I asked for the following, I don't know why I don't know why I am listing in the application, I didn't expect this much, so the last question is option 3 so finally the B version is coming, I will provide all the options like this, so wait for it, I will make a video for it I will provide all the options, if you take this, your answers will be checked according to this So, I have given you the complete final answers in B version of 2026. So, I think according to me, our faculty and team, you have given almost correct answers. If I have done anything wrong, comment it. I will recheck and recheck and reupload it. Okay? So, this is according to me. So, I will take some time to cross-check it. So, key answers will probably be left by tomorrow or by the summer. So, wait and

20:35 see. So, I think everyone has done well. Our team has done well. I am a little confused. There is a mixed response. I don't know what will happen. So, wait for the key answers and I will cross-check it. I am correct in this, this is the video for you, if you like the video press the like button, further you will get counselling, personal guidance, if you need ping me, contact me, before that don't forget to subscribe, like and share with your friends, thank you, thanks for watching.
