Question

The difference between 2 numbers is 30 and one number is 4 times the other find the number.

Answer 1

Let us assume, x and y are the two numbers

Given:

x – y = 30 ----------1

Also given:

x = 4y ------------2

Substitute the value of x from equation 2 in equation 1

4y – y = 30

3y = 30

y = 10

Therefore, x = 4y = 4 * 10 = 40

The two numbers are 40 and 10.
