Answer 1

Given:

A school uniform shop has 3 red polos, 8 white polos, and 15 grey polos.

To find:

The number of red polos that will be sold out of the next 182 polos.

Solution:

A school uniform shop has 3 red polos, 8 white polos, and 15 grey polos. It means red, which and grey polos are sold in the ratio 3:8:15 respectively.

Let the number of red, which and grey polos are 3x, 8x and 15x respectively.

Total number of polos = 182

`3x+8x+15x=182`

`26x=182`

Divide both sides by 26.

`x=(182)/(26)`

`x=7`

Now,

`\text{Red polos}=3x`

`\text{Red polos}=3(7)`

`\text{Red polos}=21`

Therefore, 21 red polos will be sold out of the next 182 polos.
