A 15-member group has two individuals aged 18 and 23. When excluded, the average age of the rest increases by 3 years. Find the average age of all members.
ATQ, Average age 'u' years. Total age 15u. Sum age 18+23=41. Remaining 15u−41. New average u+3. Equation: 15u−41=13(u+3) Solve: 15u−13u=41+39 ⇒80⇒2u=80 ⇒u=40
