Question

In a fruit shop Ratio of oranges and apples is 2:5 if there are 60 apples so what is the number of oranges

Answer 1

Let total fruit be x.
Then number of apples
$x \times \frac{5}{2 + 5} = 60 \\ \frac{5x}{7} = 60\\ x = \frac{60 \times 7}{5} = 84$
Therefore number of oranges is
$84 \times \frac{2}{2 + 5} \\ = 84 \times \frac{2}{7} = 24$

Answer 2

no of oranges = 2x

No of apples = 5x =60

x = 60/5 = 12

no of oranges = 2 x 12 = 24
