Question

answer with explanation​

Answer 1

Answer:

15/2 days

Step-by-step explanation:

Let us represent Ajay as Á and Vinod as V.

Given , Ajay and vinod together do the work in 3 days.

In one day, they will together do 1/3th part  of the work.

=> 1/ A + 1/V = 1/3 --- [1]

Vinod alone can do the work in 5 days.

In one day, Vinod can do 1/5th part of work.

=> 1/V = 1/5 ------- [2]

Substitute [2] in [1]

1/A + 1/5 = 1/3

=> 1/A = 1/3 - 1/5 = 2/15.

Thus Ajay will take 15/2 days to complete the work alone.
