Answer to Q130

If A gets 25% more than B and B gets 20% more than C, how much does C get out of $740?

If A gets 25% more than B
A = 125% of B
A = 1.25B (eqn 1)

B gets 20% more than C
B = 120% of C
B = 1.2C (eqn 2)

how much does C get out of $740?
So, A + B + C = 740 (eqn 3)

From eqn 1 and eqn 2,
A = 1.25 (1.2C)
A = 1.5C (eqn 4)

From eqn 3,
1.5C + 1.2C + C = 740
3.7C = 720
C = 720 ÷ 3.7
C = 200

Answer: $200
