Question

mohit can do three times as much work as kushal. They together finish a work in 14 days. In how many days can mohit alone finish the work.

Answer 1

Let the amount of work done by Kushal be x
⇒Mohit's work = 3x
According to question :-
Khusal work + Mohit work = 14 days
⇒ 3x+x=14
⇒4x=14
⇒x=14/4
⇒x=7/2
means Khusal's contribution in the work is 7/2
⇒Mohit's work = 3*7/2 = 21/2
so, Mohit can approximately complete the work in 10 and half days.

Answer 2

Mohit=Kushal* 3 (*is into)...
Therefore,
Mohit/3=Kushal
As Mohit+Kushal=14
Mohit+Mohit\3=14
Lcm
3M+M=14*3
4M=42
M=21/2
M=10.5
There fore MOHIT takes 10 days and another half day to complete his work!!!!
