0:00 Hello friends, you all are heartily welcome to a new video. In today's video we are starting with time and work. This is part one. This is how questions are asked, i.e. MDH is a formula, through which they have to be solved. As many types as can be made. So in part one we have taken some questions which are very important. We will move from simple to difficult, step by step, so that you people do not face any kind of problem in understanding them. First of all, we will memorize the formula, like m is m1 d1 and h1 upon w1. We will memorize the formula, after that we will proceed further, you will be able to remember it very easily. Here it will be m2
0:46 d2 and h2 upon w2. Now we will understand this formula here. Once we look at this formula, after that it has been repeated here, like we have assumed m1, here there is m2, here there is d1, then here there is d2, here there is h1, then here there is h2, here there is w1, then here there is w2, so remember here that MD H M means There are so many men and women working, how many are they and here d means day, so the person works in a day like here there are 12 people, they can do a work in 8 days, so here the number of people is 12 i.e. m1 is given, day i.e. d1 is given, h how many hours is he working, such a question can be asked, that is why h1 is written here, how much work is he doing or he is making 2 meter road,
1:32 whatever it is, it is kept in dot here, in the same way other data is given here, so this formula is going to be used here, just remember this formula, in this all your questions will be solved, so let us solve the first question, after that we will move forward, we will solve all the questions through this formula, 12 people can do a work in 8 days, so here m1 will be ours, it will be 12 and d will be here, it will be aa, that is, it can be done in aa day 16 In how many days can a person do it? Here A2 is given, 16 persons. Now see here, work is getting completed on each side, that means 12 persons can do it
2:17 in 8 days and in how many days can 16 persons do that work, so this has been asked, that is, DET has been asked. Now remember here, the value which is given, like here, persons have been given, days have been given but hours have not been given, hours have not been told, so we will not keep its value in it. Alright, if any work, that means one work, two works are given like this, then it will be kept, otherwise we will not keep this also. Now, as see here, here m11 is given, so we will use the formula in this and we will remember A2 d2. And how much is ours, 12 bv how much is ours, aa how much is A2 equal to, that means how many persons, 16 t is not given, this is what has to be found out. Alright, we will write t as it is.
3:05 Now, the number is being cut directly, so we will cut it, here, you will do 12 x 8 and it will come down, here 16 will remain equal to here. d2 Okay, so here we will cut 8 one 8 8 two 16 and two will be cut off, one two and two six 12, that means how much is equal to t, so you will tell t is equal to how many six days in 6 days, here the answer for this has already come out, our option B will be corrected here. The next question is given, 12 men can build a dam in 10 days by working for 6 hours a day. Okay, now here it is said, in how many days will 12 men build a dam by working for 10 hours a day, see what is the
3:51 value of d at number one which is given here, so ours is given here and days are also given in it and hours are also given, so we will apply this formula here, okay, just double it here, m2 is given, people are given, hours are also given, that means d2 and here it will become h2, we just have to keep this value in it, one work has been given, it is talked about building only one dam, so here w is not talked about, so look here the ev which is given is 12, We will keep 12 and d and how much is given in 10 days and how many hours do they work, so you will tell 8 hours m2, that means how many people are there for the second time, 12 hours. Now see, here the
4:38 number of days was asked, that means the value of d2 is not given, so d2 will be written like this and here the hours given are of 10 hours of work. Okay, in this way, whenever you want to solve in this way, in one line, if it is given on this side, then you can directly cut them, so 10 goes by 10 and 12 goes by 12, okay, then d2 will be equal to how much will be in a day, that means the value of d2 becomes eight. Now these are our days, that means that dam will be built in a day. See, this is a very easy question. Now their level is increasing a little. As our questions increase, their level will increase. Next question is given, 20 people, working for 8 hours per day, can
5:24 dig a pond in 12 days. How many hours per day will 24 people work to dig a pond twice as big in 14 days. See, the data given here is Our data is given as m1 i.e. how many people are there here, so you will tell 20, we will first understand the data and then solve it, 7 hours i.e. h is given, h1 is given, working for 7 hours, okay, in how many days are we completing it, so in 12 days i.e. how many d1 is given, 12 days are given, our second data is given as 24 people, i.e. this is m2, how many are there here, 24 people, how many hours will they work per day, so here we have to find out the hours, i.e. h2 is not given, we will put a
6:09 question mark here and the work that we are doing here, w in this, that is, the work that is being done, we dig a pond, now here we will see how many days we have, i.e. for how many days will we dig, so 14 days have been given, that means it will become 14 here, okay and w here is two, now see here, after working, we dig a pond twice as big, so i.e. here there was a pond, we make that pond twice as big, that means w will become two here, so this time our formula will be m1 d1 and upon w1 We will place it here in the same way, m2, d2 and h2, our w2, now we will keep their values in it in
6:57 this way, the data will take some time to explain to you people, we could have placed it directly, but for the sake of explaining, how much is ours, 20 and ours will see how much is 12 and how much is ours, h has been given, how much is d in up, let us keep it equal to this, how much is a2, how much is 24, 14 is given, so we will write 14 and here it is given that h2, a2 is not given, then we will write it like this, what will be in place of d in up, it will be 2, just now we had told that the numbers above can be cut and the numbers below can be cut, we can cut the numbers so we can cut them here directly, 12 one 12 and
7:43 12 two 24 and two will be cut from two in this way, okay now see here 14 is seven and 7 two 14 and two one plus two and it will be added here 10 times, okay, so two will be cut 10 times, so How much is h2? You will tell that h2 is equal to 10. If we work for 10 hours per day, then it will come to h2, that is, hours will come. So, option A here will be our correct answer. So, it was said that how many hours should 24 people work per day? If they can dig a pond twice as big in 14 days, then how many hours per day will they take? So, you will tell that if they work for 10 hours per day, then
8:31 they can dig a pond twice as big in 14 days. In this way, the result came out here. The next question was given that 24 labourers can build a road in 15 days by working for 8 hours. In how many days will 48 labourers build a road thrice as long by working for 6 hours per day? This is in the same manner as question number three. So, there are 24 labourers, so we will write 24 labourers. Now, we will write how many days here, that is, 15 days. Then how many hours do they work? So, they are working for 8 hours. Now, they are building a road here. How many roads will it take? Okay, so it was said that they can build one road. Our next data was given. 28
9:17 labourers. Okay, here it was asked that if we build a road three times longer, then in how many days? So we have to tell the number of days d2 here. It was not given, so we will keep d2 here. They were working for 6 hours. It was said that three times the road was being built here. That means we will keep three values here. Our data has been kept on this. Now we will solve it. 24 one 24 24 dna 48. Okay, now it has been cut by two. Two one two two ch aa. Okay, now it will be cut by three. Ekti will be here. Dna 6 and two onem two 2 dni 4. Now the numbers below have also been cut.
10:04 Now the upper part is left. So what will be our d2? See, all the numbers here have been cut. Now 15 is left here. Two 15 d 30. So now in 30 days, we can dig three times the pond. Okay, so how many days will it take to build it? You will tell 30 days. So in this way, the right answer to question number four will be Option B will go correct answer will be 30 days next question given 12 people earn 448 480 by working 6 hours per day how much money will 18 people earn by working 12 hours per day see here there are 12 people right it was said per day means it will be only one so there is no problem
10:50 here and how much are they earning by working 8 hours they are earning 480 it has been told that 12 people are earning 80 by working 8 hours so how much money will 18 people earn per day by working 12 hours so here we have to find out the money just see our value we have to understand the nature solve in the same way now we can cut the numbers here right so from 12 we can cut directly up and down also 12 is cutting here also so we can cut the numbers above 12 from 12 here right now we can cut from 8 here also 8 one 8 and 8 6 48 so here zero will remain i.e.
11:36 this cross will be applied 60 times now It will multiply, it will multiply this here, okay then w2 will become equal now see, there was only one left here, so this will remain w with double, now the number here will multiply, that is, it will become 18 times 60, now we will multiply here, we will multiply 6 8 48, eight minus four 6 one 6 4 10, that is 1080, so how much money will you earn, then you will tell 80, that is, option B, its correct answer will be here, see, in this way, to solve the questions, this MDH formula is applied, so the MDS formula has to be prepared well in this manner, after that if you solve these questions, then you will be
12:22 able to solve them very easily, we hope that today's video would have been helpful for you people, if you got any help from the video, then please like and share the video
