If an item is bought for 90 at 10% discount, then the marked price is​

Answer 1

Answer:

Let us take the marked price be x.

Then 10% discount on it = x×90/100 = 9x/10.

But, it is given 90.

So, ATQ, 9x/10=£90.

or x = £90 × 10/9.

Therefore x = £100.

Therefore marked price is £100.

sp=mp-discount

90=mp-10

mp=90+10=100
