Answer:

12 days

Step-by-step explanation:

let B will finish work in x days then,

2/10+ x/15=1

6+2x=30

2x=24

x=12 days

2nd method

A's one days work = 1/10 days

B's one day work= 1/15 days

so (a+b)'s 1 day work= 30/5=6 days

so we get by lcm method the total work is 30.

and A's 2 days work= 3×2=6

so balance work= 24 (done by B)

b's one day work= 2

so 24/2=12 days
