A grocery shop is offering a 10% discount on the purchase of Rs.500 and above. A 5% discount is given on the purchase of value above Rs.250 but below Rs.500. A discount of an additional 1% is given if payment is made instantly in cash.
He bought 25 packets of biscuits and one packet is priced at Rs.30.
Concept used:
1. Final discount percentage after two successive discounts of A% and B% = \((A + B - {AB \over 100})\%\)
2. Selling price = Marked Price × (1 - Discount%)
Calculation:
Total billed price = 25 × 30 = Rs. 750
Since he paid in cash, he would get two consecutive discounts of 10% and 1%.
So, final discounts = 10 + 1 - (10 × 1)/100 = 10.9%
Now, he would have to pay = 750 × (1 - 10.9%) = Rs. 668.25
∴ He would have to pay Rs. 668.25.
