alleryIf the ratio of two quantities is 3 : 4 and the antecedent is 15, the consequent is
A20
B60
C16
D22
Answer & Solution
Correct answer: A. 20
1. In a ratio a : b, a is called the antecedent and b is called the consequent.
2. Given 3 : 4 and antecedent = 15, set up 3/4 = 15/x.
3. Cross-multiplying: 3x = 60, so x = 20.
4. Hence the consequent equals 20.
