Question

One number is four times another number. If the smaller number is subtracted from the larger number, the result is the same as as if the smaller number were increased by 30. What are the two numbers?

Answer 1

let the smaller number be x

then larger number will be 4x

smaller number subtracted from bigger number = 4x-x

smaller number increased by 30 would be:

x+30,Then the equation :

= 4x-x=30+x

= 3x-x=30

= 2x=30

= x=30/2

= x=15
