Answer 1

Answer:

A one day work =1/10

B one day work =1/12

C one day work =1/15

a worked for 2days

So his total work =1/10=1/5

work done by all of them in one day =1/10+1/12+1/15=25/100=1/4

Let the work is completed in x days.

A's two days work + B's work in (x-3) days + C's total work=1

1/5 +(x-3)* 1/12+ x* 1/15= 1

12+5x-15+4x=60

9x-3 =60

9x =63

x=7
