L&T Company Numerical Ability Time and Work

X can have a piece of work done in 15 days, Y can work five times faster than the X, Z can work three times faster than X. How many days will they take to do the work together ?

Read Solution (Total 1)

X shared work equation
t/15+ 5t/15 + 3t/15 =1
t+5t+3t = 15

invert the dividing fraction and multiply, results
9t = 15
t = 15/9 together working
