Question
A seller sold a product for Rs. 1152 after giving two
identical discounts of x% each on the marked price of Rs. 1800. What is the value of x?Solution
ATQ,
3600 × (100 – x)% × (100 – x)% = 2025
1800 × (100 – x)% × (100 – x)% = 1152
0.18 × (100 – x)² = 1152
(100 – x)² = 6400
100 – x = 80
x = 20
So, the value of ‘x’ is 20%
