The product of two numbers is 7260. If one number is 15 times the other number, find the numbers.

ANSWER
It is given that
Product of two numbers =7260
Consider one number = x
Second number = 15x
It can be written as
15x * x=7260
15x ² =7260
By further calculation
x ² =
= 484
x=
= √2×2×11×11
So we get
= 2 × 11
= 22
Here,
One number = 22
Second number = 22 × 15 = 330

I hope my answer is helpful for you...
Let the first number be x.
As the second number is 15 times the first number,
the second number is 15x.
Their product = 7260
According to condition,
15x × x = 7260
or, 15x² = 7260
or, x² = 7260/15
or, x² = 484
or, x = √484
or, x = √2×2×11×11
or, x = 2 × 11
or, x = 22
So, the first number = x = 22
and the second number = 15x = 15 × 22 = 330
Hence, the numbers are 22 and 330.
