Q2 of 157 Page 38

Frame and solve the equations for the following statements:

Two numbers are in the ratio 5 : 3. If they differ by 18, what are the numbers?

Let the numbers be 5x and 3x


Then according to the question,


5x – 3x = 18


⇒ 2x = 18



⇒ x = 9


⇒ 5x = 5 × 9 = 45


⇒ 3x = 3 × 9 = 27


Hence, the numbers are 45 and 27.
