Question: The average of 10 numbers is 50. If one number is replaced by 70, what will be the new average?

Options:

  1. 50
  2. 52
  3. 54
  4. 56

Correct Answer: 52

Solution: 

The sum of the 10 numbers is 10 * 50 = 500. Replacing one number with 70 gives a new sum of 500 - x + 70. The new average is (500 - x + 70) / 10. Since x is 50, the new average is (500 - 50 + 70) / 10 = 52.
