Answer:
27
Step-by-step explanation:
The average age of 10 students is 20.
The sum of ages of 10 students = 10*20=200
if 4 students join the group, the average age increases by 2 years.
then, the sum of ages of 14 students will be
14*22=308
The sum of ages of 4 students will be
308-200=108
The average age of 4 students will be
108/4=27
