​

This was about a discount theorm

Answer 2

Answer:

let the marked prize be 100

10% discount =100-10% of 100

=100-10=90

20% discount=90-20% of 90

=90-18=72

30% discount=72-30%of 72

=72-21.6=50.4

so we have to 50.4 rupees instead of 100 rupees

it we get discount of 100-50.4= 49.6 rupees

In percent we get total discount = 49.6/100 ×100

= 49.6%
