Ena was born 4 years. after her parents' marriage. Her mother is three years younger than her father and 24 years older than Ena, who is 13 years old. At what age did Ena's father get married ?
- (a) 22 years
- (b) 23 years ✓ UPSC's answer
- (c) 24 years
- (d) 25 years
Why the answer is (b)
• Ena is currently 13 years old, and her mother is 24 years older than her, making the mother's current age 13 + 24 = 37 years.
• The mother is three years younger than the father, so the father's current age is 37 + 3 = 40 years.
• Ena was born 4 years after her parents' marriage, meaning the marriage took place 13 + 4 = 17 years ago.
• To find the father's age at the time of marriage, subtract the number of years since the marriage from his current age: 40 - 17 = 23 years.
• Therefore, Ena's father was 23 years old when he got married, which corresponds to option (b).
Why the other options are wrong
- (a) 22 years
- Option (a) is incorrect because it results from an arithmetic error in calculating the father's age at marriage, yielding 22 instead of 23.
- (c) 24 years
- Option (c) is incorrect because it confuses the mother's age difference with the father's age at marriage, resulting in 24 instead of 23.
- (d) 25 years
- Option (d) is incorrect because it adds the 4-year gap incorrectly or miscalculates the father's current age, leading to 25 instead of 23.
