Question

Mohit and suresh can do piece of work in 12 days while suresh alone can finish it in 30 days in how many days can mohit alone finish the work solve full please answer

Answer 1

given,
Mohit &Suresh can do a piece of work in 12 days
Suresh can do a piece of work in 30 days
let,
Mohit alone finish the work in x days
so,
1/30 + 1/x = 1/12
=> 1/x = 1/12 - 1/30
=> 1/x = 1/20
=> x = 20
hence, Mohit takes 20 days to finish the work alone

Answer 2

M+S can do in12days
M+S ,work= 1/12
S do in 30 days
S work is 1/30,
1/12-1/30,5-2/60,3/60,1/20 work has left which is done by M .hence mohan can finish remaining work in 20 days.
