Question

b) The average age of Pratik, Debashis, Sunayana, and Buddhi is 16 years. If the age of the first three children are 7 years, 13 years, and 20 years respectively, how old is Buddhi?​

Answer 1

14 years old

Explanation:

To determine the age of Buddhi, use the formula 16 = (7 + 13 + 20 + b)/4, where b is the age of Buddhi. Solving this equation, we get b = 14 years. Therefore, Buddhi is 14 years old.
