Answer:
Russell: 40 pounds; Sarah: 100 pounds; and Terry: 160 pounds.
Step-by-step explanation:
The three different amounts of money are 2x, 5x and 8x, or 15x.
Terry gets 8x, whereas Russell gets 2x, and 8x - 2x = 120 pounds.
Solving for x, 6x = 120 pounds, and so x = 20 pounds.
Russell gets 2(20 pounds); Sarah gets 5(20 pounds); and Terry gets 8(20 pounds), or 40 pounds, 100 pounds and 160 pounds. Note that 40 pounds is 120 pounds less than 160 pounds, as required by the problem.
