Question

Paul, Colin and Brian are waiters.

One night the restaurant earns tips totalling £77.40.
They share the tips in the ratio 2:3:4.
How much more does Brian get over Paul?

Answer 1

Add the ratios together: 2 + 3 +4 = 9

Divide the total tips by 9:

77.40 / 9 = 8.60

Multiply each portion of the ratio by 8.60:

2 x 8.60 = 17.20

3 x 8.60 = 25.80

4 x 8.60 = 34.40

The ratios are in order of the people:

Paul got 17.20

Colin got 25.80

Brian got 34.40

Brian got 34.40 - 17.20 = 17.20 more than Paul
