Question

Sohan works 1/10 a day and together with Deepak completes the work in 6 days. In how many days will Deepak alone complete the work?

Answer 1

Answer:

Deepak will take 15 days to finish the work alone.

Step-by-step explanation:

Work done by them together in one day

= 1/10 + 1/x = 1/6

Take L.C.M method  = 10x  

So,

x + 10/10x = 1/6

on cross multiplying we get.

6(x +10) = 10x

6x + 60 = 10x

10x - 6x = 60

4x = 60

x = 60÷4

x = 15

So, Deepak will take 15 days to finish the work alone.
