  1. Question 1

    Q1. The average of 10 numbers is 20. If each number is increased by 5, what will be the new average?

    • A) 20
    • B) 25
    • C) 22.5
    • D) 30

    Answer: 25

    Explanation: The sum of the 10 numbers = 10 * 20 = 200. After increasing each by 5, the new sum = 200 + 10 * 5 = 250. So, the new average = 250 / 10 = 25.
