alleryThe ratio compounded of 2 : 3, 9 : 4, 5 : 6 and 8 : 10 is
A1 : 1
B5 : 1
C3 : 8
D1 : 5
Answer & Solution
Correct answer: A. 1 : 1
1. Compound ratio of (a : b) and (c : d) is ac : bd.
2. Multiply antecedents: 2 * 9 * 5 * 8 = 720.
3. Multiply consequents: 3 * 4 * 6 * 10 = 720.
4. So compound ratio = 720 : 720 = 1 : 1.
