Question

Serenity picked 75% of the apples of a tree in her backyard. If she picked 30 apples, how many apples were on the tree to begin with?

Answer 1

Given:

Serenity picked 75% of the apples of a tree in her backyard.

She picked 30 apples.

To find:

The number of apples on the tree in the beginning.

Solution:

Let x be the number of apples on the tree in the beginning.

Serenity picked 75% of the apples of a tree in her backyard.

Number of apples picked = 75% of x

=
`(75)/(100)x`

=
`(3)/(4)x`

She picked 30 apples.

`(3)/(4)x=30`

Multiply both sides by 4.

`3x=4* 30`

`3x=120`

Divide both sides by 3.

`x=(120)/(3)`

`x=40`

Therefore, the number of apples on the tree in the beginning is 40.
