Question

A number is four times another number .if the larger number is 10 more than twice the smaller number,find the two numbers

Answer 1

Let us assume, x and y are the two numbers

Given:

x = 4y -----------1

Also given:

x = 2y + 10 -------2

Substitute the value of x from equation 1 in equation 2

4y = 2y + 10

2y = 10 y

y = 5

Therefore, x = 4 * y = 4 * 5 = 20

The two numbers are 20 and 5.
