Answer 1

Answer:

I think 12 days were B take to complete their incomplete work

Answer 2

Answer:

Answer:37 2/3

Time taken by A to complete the work= 30days

Work done by A in 1day= 1/30

Time taken by B to complete work= 40days

Work done by B in 1 day= 1/40

Work done by (A+B)= 1/30+1/40= 7/120

Remaining work= 1-7/120= 113/120

Time taken by B to complete the rest work= 113/120×40= 113/3= 37 2/3.
