Question 29

If two successive discounts of 20% and 30% are given, then what is the net discount (in %)?

Solution

Let list price = Rs. $$100x$$

After first discount of 20%, price = $$100x \times \frac{(100-20)}{100}=80x$$

After second discount of 30%, price = $$80x \times \frac{(100-30)}{100}=56x$$

=> Equivalent discount = $$\frac{100x-56x}{100x} \times 100$$

= $$44\%$$

=> Ans - (B)
