Machine X is 3 times as efficient as Machine Y. If Machine Y prints 3000 pages in a day, how many pages can Machine X print in 1.5 days? Correct Answer 13500

Given:

Machine X is 3 times as efficient as Machine Y. Machine Y prints 3000 pages in a day.

Formula used:

/ W1 = / W2, where, E is efficiency, D is the number of days, and W is work done.

Calculation:

Let required number of pages that can be printed by X in 1.5 days be ‘W”

According to question:

3 × (3/2) × (1/W) = 1 × 1 × (1/3000)

⇒ W = 3 × (3/2) × 3000 = 9 × 1500 = 13500 pages

∴ Machine X print 13500 in 1.5 days
