Question

Three students share a house .Tom has a bigger room they decide to share the rent in a ratio of 3:2:2 the total cost of the rent is 700 how much does Tom pay per month

Answer 1

$300 because you do 3+2+2 which gives you 7 so you divide 700 by 7 to get 100 then you do 100•3 to find out how much Tom payed

Answer 2

300

Explanation:

The bigger room is to share in the ratio of 3 : 2 : 2.

The total cost of the rent is 700. Let x is the amount paid by per student. It can be calculated by summing up the ratios and equating it equal to 700.

`3x+2x+2x=700`

7x = 700

x = 100

Amount paid by Tom is 3x or 300. Hence, this is the required solution.
