Solution

Given that, in normal days shopkeeper give 25% discount and during the off season, he offered 30% discount over and above the existing discount and the marked price of skirt = Rs. 1200.

⇒ For normal days:

Discount = `25/100 xx 1200`

= Rs. 300

∴ The skirt price will be = Rs. 1200 – Rs. 300

= Rs. 900

And now for off season:

30% discount over and above the existing discount will be there

⇒ Discount = `30/100 xx 900`

= Rs. 270

∴ Skirt price now will be = Rs. 900 – Rs. 270

= Rs. 630
