Question

the sum of two numbers is 80 . if the larger number exceeds four times the smaller number by 5 what is the smaller number ​

Answer 1

Given, sum of two numbers is 80.

Let the smaller number be x

Thus the larger will be 80−x.

Also given, larger number exceeds four times the smaller number by 5.

Therefore, 80−x=4x+5

⇒5x=75

⇒x=15

Thus the smaller number is 15.
