A. 600

B. 800

C. 1000

D. 1200

E. 1500

I know this question is relatively symol if make an equation in one vaibale ...

I tried to do it by applying the fundamental of A = Jobs per min * time ( the way we typically solve the work problems ) and i was stuck

I did jobs per minute A , 1/60

combined rate = 1/24

so rate of b = 1/24 - 1/60 = 1/40

but could not arrive at the solution ... i tried to form the equation by assuming x as the total numbe of pages So x/60+ x+5/40 = cld nt take ot forward from here

kindly see where am I losing the track !

Solution by

Bunuel as per the GMAT Club Math Book
