Question 1
The average age of a family of 7 members (James, Julian, Ritu, Nidhi, Julia, Neelam, Christopher) is 26.0 years. If Christopher (age 44) leaves the family, what will be the new average age?
Total age = 26.0 × 7 = 182
After Christopher leaves: 182 - 44 = 138
New average = 138 ÷ 6 = 23
After Christopher leaves: 182 - 44 = 138
New average = 138 ÷ 6 = 23
