If 40% of P equals one-half of Q equals one-eighth of R, then find the ratio P : Q : R.

1. 5 : 4 : 16
2. 4 : 5 : 16
3. 2 : 5 : 8
4. 4 : 5 : 8

Correct answer: 5 : 4 : 16

Solution

Letting each expression equal k gives P = 2.5k, Q = 2k, R = 8k, so P:Q:R = 2.5:2:8 = 5:4:16 after doubling. The correct ratio is 5 : 4 : 16.
