Question 1
The average age of 5 people is 32. If Piya (age 21) leaves and a new person joins, the average becomes 35. Find the age of the new person.
Initial total = 32 × 5 = 160
After Piya leaves: 160 - 21 = 139
New total = 35 × 5 = 175
New person's age = 175 - (139) = 36
After Piya leaves: 160 - 21 = 139
New total = 35 × 5 = 175
New person's age = 175 - (139) = 36
