Answers
Given : Average age of 36 children of the class is 15 years. 12 more children joined whose average age is 16 years.
To Find : What is the average age of all the 48 children together?
Solution:
Average age of 36 children of the class is 15 years
=> Age of 36 children = 36 * 15
=> Age of 36 children = 540 years
12 more children joined whose average age 16 years
=> Age of 12 more children = 12 * 16
=> Age of 12 more children = 192 years
Total Age = 540 + 192
= 732 years
Total children = 36 + 12 = 48
Average age of all 48 children = 732/48
= 15.25 years
Average age of all 48 children = 15.25 years
