Given:
S:M:L = 16:23:20
Total = £1180
Actual amounts for each
S:M:L = (£1180/(16+23+20)*(16:23:20)
=£(320:460:400)
Marvin takes out £100, and Lucy puts in £x, so new ratio
(8:9:12) = (320:360:400+x)
If we multiply the left-hand side by 40, we get
(320:360:480) which equals (320:360:400+x)
Can you figure out what x should be?
