Question

Three students share a house. Tom has a bigger room, so they have decided 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

Answer : Tom pay per month = £300


Explanation -

Given :

Total Rent - £700

Ratio = 3:2:2

Add the given Ratio = 3 + 2 + 2 = 7

Finding the share of Tom -

= 700 x 3/7

= 2100/7

= 300

Tom's share = £300

Hence :

Tom pay per month = £300

Answer 2

sum of ratio=7
Tom has bigger room so his ratio is high
that is 3
$toms \: share =(tom \: ratio \: \div totl \: ratio) \times total \: rent \\ = (3 \div 7) \times 700 \\ = 300$
