  • Question 1
    1 / -0

    A certain number is increased by 15% and then the result obtained is decreased by 20%. Find the net percentage increase or decrease in the number.

    Solution

    Let the number be 100.

    Increased number = 100 + 15% of 100
    = 100 + 15 = 115

    Now, this number is decreased by 20%.
    New number = 115 - 20% of 115 = 92

    Net decrease = 100 - 92 = 8
    Net % decrease = 8%
