Question 37

State whether the following statement is 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.

Answer 1

False
Let the number of boys be 5x and the number of girls be 4x.
According to the equation,
5x-4x=9
$\Rightarrow x=9$
Hence,number of boys=$5\times 9=45$
