Question

The product of 2 given numbers is 525. The two numbers are each divisible by 5, but neither of
them is 5. Which is the larger of these two numbers?

Answer 1

Answer:

Since numbers are divisible by 5, lets assume numbers are 5x and 5y.

Also, since numbers are not equal to 5, x and y cannot be 1

It is given that their product is 525

(5x) (5y) = 525

⇒ 25 xy = 525

⇒ xy =

525

25

⇒ xy = 21

Since x and y cannot be 1, only possible f actors of xy = 21, are 7 and 3

Therefore numbers are (7 × 5 = 35) and (3 × 5 = 15)

Larger of two numbers = 35
