Question

Find the single discount equivalent to two successive discounts of 25% and 10%.

Answer 1

Answer:

Formula :

Single discount equivalent = ( first discount + second discount - first discount × second discount /100 )%

Step-by-step explanation:

Single discount equivalent = ( first discount + second discount - first discount × second discount /100 )%

So , single discount = ( 25 + 10 - 25 × 10 / 100 )%

= ( 35 - 2.5 )%

= 32.5 %

Hence , two discounts of 25% and 10 % are equal to a single discount of 32.5%.
