Question 1
The average age of a family of 7 members (Lata, Ganesh, Sarthak, Revathi, John, Alex, Neelam) is 34.7 years. If Lata (age 27) leaves the family, what will be the new average age?
Total age = 34.7 × 7 = 243
After Lata leaves: 243 - 27 = 216
New average = 216 ÷ 6 = 36
After Lata leaves: 243 - 27 = 216
New average = 216 ÷ 6 = 36
