Question

Three discounts of 10%, 20% and 25% respectively in this order give an overall Effective Discount of _____.

• A. 54%
• B. 46%
• C. 42%
• D. 55%

Answer 1

The correct option is B 46%

If we take x, the solution becomes difficult.
Let us Assume the original price to be ₹100.
10% Discount gives : 100 - $\frac{10}{100}\times 100$ = ₹90
20% Discount gives : 90 - $\frac{20}{100}\times 90$ = ₹72
25% Discount gives : 72 - $\frac{25}{100}\times 72$ = ₹54
Effective Change = ₹100 - ₹54 = ₹46
Effective Discount = 46%.
