yrs, 16 yrs, 18 yrs. What is the average age of the other three students ?
​

Answer 1

Step-by-step explanation:

Average age of 6 students = 15 years

Since Average = Total no. of years/Total students

Then, total age = Average age * Total students = 15 * 6 = 90

Total ages of 3 students = 14 + 16 + 18 = 48 years

Left years = 90 - 48 = 42

Average age of 3 students = 42/3 = 14 years.
