Vedclass · Answer

(C) To find the equivalent single discount for two successive discounts of $a \%$ and $b \%$,we use the net discount formula:$	ext{Net Discount} = \left(a + b - \frac{a 	imes b}{100}ight) \%$Here,$a = 40$ and $b = 20$.Substituting these values into the formula:$	ext{Net Discount} = \left(40 + 20 - \frac{40 	imes 20}{100}ight) \%$$= (60 - \frac{800}{100}) \%$$= (60 - 8) \% = 52 \%$Therefore,two successive discounts of $40 \%$ and $20 \%$ are equivalent to a single discount of $52 \%$.

Two discounts of $40 \%$ and $20 \%$ are equal to a single discount of what percentage?
