Question

The marked price of a mobile set is Rs 9,600 and 40% discount is allowed to make 20% profit. By what percent is the discount to be reduced to increase the profit by 10%?​

Answers

  1. Answer:
    5%
    Step-by-step explanation:
    price after discount :
    9 600 – 9 600×40%
    = 5760
    Original price (price without profit) :
    let x be the original price of the device.
    x + x × 20% = 5760
    Then
    x = (5 760×100)÷120
      = 4 800
    Original price increased by 30% :
    4 800 + 4 800×30%
    = 6 240
    the discount needed to increase the profit by 10% :
    [(9 600-6 240)÷9 600]×100
    = 35%
    Then
    to increase the profit by 10% ,we have to reduce
    the percent of discount to :
    40% – 35%
    = 5%
