Question

There are 30 members in a team. If the ratio of the number of boys and girls is $8:7$, then there are boys in the team.

• A. 16
• B. 14
• C. 15
• D. 19

Answer 1

The correct option is A 16

Let the number of boys and girls in the team be $8x$ and $7x$.

The total number of team members is $8x+7x$ i.e., equal to 30.

$\Rightarrow 8x+7x=30\Rightarrow 15x=30\Rightarrow x=\frac{30}{15}\Rightarrow x=2$

So, the number of boys, $8x=8\times 2=16$.
