Question

Dave, colin and emma share money. Colin gets 3/10. Emma and Dave share the rest in ratio 3:2. What is Dave's share?

Answer 1

7/25

Explanation:

You want to know Dave's share if he and Emma split the remainder in the ratio 3:2 after Colin claims 3/10 of the money.

Rest

The remaining money after Colin's claim is 1 -3/10 = 7/10.

Dave's

Of this Dave gets a 2/(3+2) = 2/5 share.

Dave's share of the initial amount is ...

(7/10)(2/5) = 14/50 = 7/25

Dave's share is 7/25 of the money, or 28%.
