A's 10 days work = (1/25*10)= 2/5 ; remaining work = (1-2/5) = 3/5
(A+B)'s 1 day work = (1/25+1/20) = 9/100
9/100 work is finished by (A+B) In 1 day.
3/5 work is finished by (A+B) in (100/9* 3/5) days = 20/3 days
Total time taken = (10+ 20/3) = 50/3 days

              Remaining work = (1-5/6) = 1/6
1/6 work is done by boy in 6 days.
Whole work will be done by the boy in (6*6) = 36 days

1 man = 3/2 boys , 8 men = (8*3/2) boys = 12 boys
(4men + 9 boys) = (4*3/2 +9) boys = 15 boys
Now, 12 boys dig it in 20 days.
1 boy digs it in (20*12) days.
15 boys will dig it in (20*12)/15 days = 16 days

Q 7 - If 1 men or 2 ladies or 3 kid can do a bit of work in 44 days , then the same bit of work will be finished by 1 men , 1 ladies and 1 kid in

3 boys 1 day's work = 1/44 ⇒1 boys 1 day work = 1/132
(1 man + 1 women + 1 boy)'s 1 day work =  (1/44+ 1/88+1/132 )= (6+3+2)/264
= 11/264 = 1/24
