Three men, A, B and C agree to share the expense of a fishing expedition in the ratio 2:3:4.

A pays $25 for the hire of the boat, B pays $70 for the meal and C pays $49 for traveling expenses.
How much must A and C pay B to settle their agreed shares?

apparently

2x+3x+4x = 25+70+49
9x = 144
x = 16

So, A:B:C = 32:48:64

Now figure the shortfalls.
