Question

A box has 24 balls in it. If ${\frac{3}{4}}^{th}$ of them are red, how many balls are not red in colour?

• A. 18
• B. 12
• C. 6
• D. 4

Answer 1

The correct option is C 6

Number of balls in the box = 24
${\frac{3}{4}}^{th}$ of the balls in the box are red balls.
Number of red balls = $24\times \frac{3}{4}$
= $\frac{24\times 3}{4}$
= $\frac{72}{4}$
= 18

18 balls are red in colour.

So, number of balls not red in colour
= 24 - 18 = 6
