If m : n = 1 : 2 and p : q = 3 : 4, then what is (2m + 4p) : (n + 3q) equal to ?
Answer
The correct answer is A: 1 : 1. Let m = 1, n = 2, p = 3, q = 4. Then 2m + 4p = 2 + 12 = 14 and n + 3q = 2 + 12 = 14.
- A.1 : 1✓ Correct
- B.1 : 3
- C.2 : 1
- D.2 : 3
Let m = 1, n = 2, p = 3, q = 4. Then 2m + 4p = 2 + 12 = 14 and n + 3q = 2 + 12 = 14. So the ratio is 14 : 14 = 1 : 1.
