Question

find a single discount equivalent to three successive discounts of 20%, 5% and 1%. Please answer me this question urgently​

Answer 1

Answer :

Discount = 75.24 %

Explanation :

According to the question :

Let the marked price be ' Rs. 100 '

x1 = 20% , x2 = 5% and x3 = 1%

Single Discount = ( 1 - x1 % ) ( 1 - x2 % ) ( 1 - x3 % ) × Marked price

=> ( 1 - 20 / 100 ) ( 1 - 5 / 100 ) ( 1 - 1 / 100 ) × 100 %[ LCM = 100 ]

=> ( 100 - 20 / 100 ) ( 100 - 5 / 100 ) ( 100 - 1 / 100 ) × 100 %

=> ( 80 / 100 ) × ( 95 / 100 ) × ( 99 / 100 ) × 100 %

=> 75.24 %

❥ So, It's Done ❥ !!
