Question

Julie, Kelly and Lou win some money at the Bingo in the ratios

2:5:12 respectfully. Kelly won £66 more than Julie.
b) How much did they win altogether?

Answer 1

£418

Explanation:

The ratio can be expressed as 2x : 5x : 12x ( x is a multiplier ), then

5x = 2x + 66 ( Kelly won £66 more than Julie )

Subtract 2x from both sides

3x = 66 ( divide both sides by 3 )

x = 22

Thus

2x = 2 × 22 = £44

5x = 5 × 22 = £110

12x = 12 × 22 = £264

------------- +

£418 ← total amount won

Answer 2

£418

Explanation:

i answered part of this earlier

julie = 2

kelly = 5

lou = 12

5-2 = 3

3 = £66

£66/3 = £22

2+5+12 = 19

19 x £22 = £418
