Question 120

Successive discounts of 20% and 10% are equivalent to a single discount of:

Solution

Let Marked price = Rs. $$100$$

After 1st discount of 20%, price = $$100-(\frac{20}{100}\times100)$$

= $$100-20=80$$

After 2nd discount of 10% (on changed price), selling price = $$80-(\frac{10}{100}\times80)$$

= $$80-8=72$$

$$\therefore$$ Net discount % = $$\frac{(100-72)}{100}\times100=28\%$$

=> Ans - (A)
