Answer 1

Hi friends i also. Want to know the answer to the same

Answer 2

A is 50 % more efficient than B

Efficiency ratio A:B = 150:100 = 3:2


efficiency of (A+B) = 3+2 =5

total work = efficiency× time = 5×15 = 75

Time taken by A alone to complete work = Total work / efficiency of A

= 75/3

= 25 days


Hope it helps
