Their nresent ages are:​

Answer 1

Answer:

15 days

Step-by-step explanation:

vikas 1 day work= 1/10

vikas and mohan 1 day work= 1/6

mohan 1 day work= 1/6-1/10= 1/15

so mohan takes 15 days to complete the work.

Answer 2

Answer:

The correct answer is option C

Step-by-step explanation:

Vikas and Mohan together can complete the task in 6 days. So, in one day, they will complete 1/6 part of the task. Therefore, (Vikas + Mohan)'s one-day work will be =1/6

Similarly, Vikas's one-day work =1/10

Therefore, Mohan's one day work =(1/6) - (1/10) = 2/30 = 1/15

In one day Mohan completes the 1/15 part of the work so he will complete the entire work in 15 days.
