Question

guys plz solve this question

Answer 1

(A+B)'s 1 day work= 1/8
(B+c)'s 1 day work= 1/12
(A+B+C)'s 1 day work= 1/6

adding we get:
2(A+B+C)'s 1 day work=(1/8+1/12+1/6)
=9/24
=3/8
=3/8×1/2=3/16
now,a,b,c together can do it in 16/3 days
now ,A's one day work =(a+b+c one day work)
-(b+c)'s one day work =1/6-1/12=4-2/24=2/24=1/12= 12 days
similarly, find c.....
