Answer 2

Answer:

Colin gets 1/5th of the money

Step-by-step explanation:

Let the total money which is to be shared be M.

Caroiline gets 1/10 of the money, i.e, M/10

Colin and Sarah share the rest in ratio 2:7

Money with Colin = 2x

Money with Sarah = 7x. (x be a constant)

2x + 7x = M - M/10

9x = 9M/10

1x = M/10

Colin gets 2x = 2M/10, i.e, 1/5th of the money
