Q: The difference between the ages of Radha and Murari is 12 years. Five years ago, the sum of their ages was 28 years. If Radha is older than Murari, find Murari’s present age (in years).
  • A. 17
  • B. 13
  • C. 15
  • D. 25
Correct Answer: Option B - Let the present age of Radha is x years and the present age of Murari is y years. x – y = 12 ........ (i) x – 5 + y – 5 = 28 x + y = 38 ......... (ii) from equation (i) and (ii) x = 25 years y = 13 years Hence the present age of Murari is 13 years.
