[@getting_life_together]

41:50 hw1 . answer is 12 1/2 days Hw2. Answer. 6 6/7 min

[@Artwithnam]

I always solve by random approach and it hardly takes few seconds ❤

[@gurmanisingh2601]

Home work answer HW-1) 12.5 days HW-2) 6(6/7) mins

[@rahulingleshwar8472]

1:12:50 , it is said in question that both the pipes are opened together for 5 min , so instead of taking A+B = 5+4 = 9l / min. Sir has taken only A that is 5L per min. So instead of 5*5 it should have been 9*5= 45 then 100-45 =55 so on on completing the next steps we obtain 13.77 min.

[@BhavyaSingh-fh3be]

exactly

[@Dev-0709]

Yeah after subtracting 45 from 100 we get 55 which divided by 4 gets us 13.75. Hence after that adding the 5min they worked together we get 18.75. So both of you are very wrong

[@aryagupta03]

[@VanshikaKansal-te8bl]

[@mansisukhdeve]

your teaching is so amazing sir..... Thankyou so muchhh ❤❤

[@riyaagrawal-0019]

The standard approach was actually easy. But here all the questions are solved in random approach. Bounced

[@krishnabhardwaj3549]

I also solved questions by standard approach

[@SriArpit23]

But i think random approach was much better than standard approach.... because of calculation

[@SAMEERChoudhary-yu8pc]

❤

[@anbhithakur4938]

Sso true 😢

[@ronakparjapati2264]

50:00 sir thoda complex bna diya....Sir ish question ko easy kiya ja sakta tha...... Solution: if one pipe A is 6 time faster than another pipe B. It's mean ration b/w pipe A and pipe B ( A:b = 6:1) it's mean if Pipe A fill tank 6 liter in 1 minute than pipe B fill tank in 1 liter in 1 minute. According to Question: Pipe B complete fill tank in 28 minutes. it's mean cistern/tank capicity is 1 * 28 = 28 liter. if both pipe open in ( 6 + 1) than tank fill 7 liter in 1 minutes so that, cistern will be complete fill if both pipe open in 28 / 7 = 4 minutes. (Answer).

[@Leo_M_10]

Hw1= 12.5 Hw2 = 6(6/7)

[@darshanchhajed]

Explain HW2

[@GovindAdityaK]

@@darshanchhajed Ratio of P:Q is 6:1 bcoz P fills 6 times faster than Q, so assume if Q fills 1 ltr/min then p must fill 6 ltr/min cuz 6 times faster. Now, Q takes 6 min to fill 6 ltrs bcoz 1 ltr/min yes ? but P only takes 1 min to fill 6 ltrs cuz 6ltr/min it can fill, so that means p takes 5 min lesser than Q to fill 6 ltrs. then use unitary method or cross multiplication method like: 5 min less = 6 ltrs 40 min less = M ltrs cross multiply gives - > 40 x 6 = 5 x M M = 240 / 5 = 48 ltrs, which is total capacity of tank. now, they ask how much time it will take if both fill together so add their ltr/mins i.e ( 6 ltr/min + 1 ltr/min = 7 ltr/min) now time taken by both to fill = total capacity / total ltr/min = 48 ltrs / 7 ltr/min = 6.8 which is also 6 6/7. ( 6/7 = 0.8) hope u understood now 👍

can you explain: A work was completed by three persons of equal ability, first one doing m hours for m days, second one doing n hours for n days (m and n being integers) and third one doing 16 hours for 16 days. The work could have been completed in 29 days by third person alone with his respective working hours. If all of them do the work together with their respective working hours, then they can complete it in about how many days?

A tub of 96 litres capacity had been filled with water by two taps A and B. A was opened for 2 hours longer than B was. If A was opened for as long as B was opened, and B was opened for as long as A was opened, then they would deliver 92 litres of water. If the two taps were opened simultaneously, the tub would be filled in 12 hours. What was the rate of A?
