Q37 of 113 Page 110

State whether the statements are true (T) or false (F).

The number of boys and girls in a class are in the ratio 5:4. If the number of boys is 9 more than the number of girls, then number of boys is 9.

False

let number of boys be 5x and girls be 4x.


∴ according to the question


⇒ 5x = 4x + 9


⇒ 5x-4x = 9


⇒ x = 9


∴ number of boys = 5x = 5 × 9 = 45


⇒ And number of girls = 4x = 4 × 9 = 36


⇒ Hence, it is not true.
