The average age of four boys Shikhar, Mukesh, Anil, and Anish is 25 years. If the ages of Shikhar, Mukesh, and Anil are 15, 25, and 29 years, then what is the age (in years) of Anish?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 3 i.e. 31.
Total age of Shikhar, Mukesh, Anil, and Anish = 4 × 25 = 100
Total age of Shikhar, Mukesh and Anil = 15 + 25 + 29 = 69
Age of Anish = 100 - 69 = 31
