Detailed Solution
Download Solution PDFLet age of P, Q, R and S be P, Q, R and S respectively.
Given,
⇒ P + Q + R = 24 × 3
⇒ P + Q + R = 72
Then,
⇒ P + Q + R + S = 30 × 4 = 120
⇒ S = 120 - 72 = 48 Years
The age of S is 48 years.
⇒ T = 48 + 4 = 52 years
Total age of five persons =

= 172
Average age of 5 persons = 172/5 = 34.4 years
