Question

For doing some work ganesh took 10 days more than gajanan. if both work together, they complete the work in 12 days. find the number of days taken ganesh to complete the work

Answer 1

let number of days taken by John be 'x'

•°• no. of days of Ganesh=x+10

BY GIVEN CONDITION,

1/x+ 1/x+10 = 12,

and then cross multiply

you will get a quadratic eq.

12x^2 - 2x - 120 - 10

solve the eq to get value of x

which is equal to no. of days john took and x+12 = no. of days ganesh took !!
