Step-by-step explanation:
total age of 15 students= 270
total age of 9 students = 108
total age of remining 6 students = 162
avg age of 6 students = 27
or
Average age of 15 students = 18 years
Total age of 15 students = 18 x 15 = 270 years
Average age of 9 students = 12 years
Total age of 9 students = 12 x 9 = 108 years
Total age of remaining 6 students = 270 - 108 = 162 years
Average age of remaining 6 students = = 27 years
Hence, the average age of remaining 6 students is 27 years.
