Question

a dealer offers a discount of 30% and 10% find the single equivalent rate of discount.​

Answer 1

Answer:

49.6%

Single equivalent discount for successive discounts of 10% and 20%.

= \left ( 10+20-\frac{20\times 10}{100} \right )\% = 28\%

Single equivalent discount for 28% and 30%.

= \left ( 28+30-\frac{28\times 30}{100} \right )\% = 49.6\%
