Question

60 children choose their favourite fruit out of apples bananas and watermelon 30% chose apples and 25% chose bananas How many children chose watermelon​

Answer 1

27 children.

Explanation:

Let's call the number of children who chose apples x. Then, the number of children who chose bananas is 0.25x. The number of children who chose watermelon is 60 - x - 0.25x = 60 - 1.25x.

Since 30% of the children chose apples, we know that:

0.30 * 60 = x

So, x = 18, which means 18 children chose apples.

And since 25% of the children chose bananas, we know that:

0.25 * 60 = 0.25x = 15

So, 15 children chose bananas.

Finally, the number of children who chose watermelon is:

60 - 18 - 15 = 27 children.
