Question

anil takes 6 days less than the time taken by varan to finish a piece of work.if anil and a run both together can finish the work in 4 days find the time taken by varan to finish the work

Answer 1

let work done by varan in one day= 1/x
,. ,. ,. anil = 1/x-6
ATQ
1/x +1/x-6 = 1/4
solving the equation we get
x = 2,12
x is not 2 as x-6 will be negative .
so, time taken by varan = 12 days .
