IBM Company Numerical Ability Time and Work

P and Q can write 135 pages in 27 hrs. P can write 3 pages in 1 hour. How much time will it take Q to write 42 pages.

Read Solution (Total 2)

Ans: 21 h
Exp:
p+q : In 27 h = 135 p, then 1 h = 5 p
and P: In 1 h = 3 p, then q in 1 h = 5-3=2
2 p q can write in 1 h
42 p q can w8 in 42/2=21 h.

ans: let the time b x

135/27hr=(3/1hr)+(42/x)

135/27=(3x+42)/x

by calculating the value of x, we get x=21 hr.
