Profit and Loss Practice Test 7

Question : 18 of 40

Marks: +1, -0

The price of an article is Rs 25. After two successive discounts by the same percentage, the price becomes Rs 20.25. If each time the discount was x%, then:

x = 9
x = 10
x = 11
x = 11.5

Validate

Solution:

Marked price = 25
SP = 20.25
Discount %

= {25- 20.25}/25× 100

Discount = 19%
Single discount

=x+x-{x×x}/100=19

2x-x^2/100=19

x^2-200x+1900=0

x=190,x=10

x = 190 is not possible
So, x = 10
