Question

solve proper​

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 = ( 20 + 100 - 20 × 100 / 100 ) %

=( 120 - 20 ) %

= 100 %

Hence , two successive discounts of 20% and 100% are equal to a single discount of 100%.
