Question

A number is increased by 12 and the new number obtained is multiplied by 5. If the resulting number is 95, find the original number.

Answer 1

Let the original number = x

According to the sum,

(x + 26) ÷3 = 18

⇒ `("x" + 26)/3 = 18`

⇒ x + 26 = 18 × 3 

⇒ x + 26 = 54

⇒ x = 54 - 26 = 28
