Answer 1

Answer:

The average of the remaining 50 numbers is 16.

Step-by-step explanation:

Average of 100 numbers is 22

∴ The sum of those 100 numbers is 100 times 22 = 2200

Again, average of 50 of those numbers is 28.

∴ The sum of those 50 numbers is 50 times 28 = 1400

∴ The sum of the remaining 50 numbers is 2200 - 1400 = 800

∴ The average of the remaining 50 numbers is $=\frac{800}{50} = 16$
