Answer:

£418

Step-by-step 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
