A rs 750 tin of cheese is offered at 8% discount and a rs 1,250 tin of butter at 20% discount. If we buy 5 tins of cheese and 3 tins of butter, what is the effective discount we get (in %)
Answers
Answer:
Step-by-step explanation:
Cost price of cheese= Rs 750
Cost price of butter = Rs 1250
Total cost price of 5 tins of cheese and 3 tins of butter (without discount)
= 5 x 750 + 3 x 1250
= ₹ (3750 + 3750)
= ₹ 7500
Discount given on cheese = 8%
Effective price of one tine of cheese after giving discount
= (750 - 8% of 750)
= ₹ 750 - 60
=₹ 690
Total price of 5 tins of cheese = ₹ 5 x 690 = ₹ 3450
Discount given on butter = 20%
Effective price of one tin of butter = 1250 - 20% of 1250
= ₹ 0.8 x 1250
= ₹ 1000
Total price of 3 tins of butter = ₹ 3 x 1000 = ₹3000
Hence, total price of 5 tins of cheese and 3 tins of butter after giving discounts = ₹ 3000 + ₹ 3450 = ₹ 6450
Hence, Total effective discount =₹ 7500 - ₹ 6450 = ₹ 1050
Total effective discount = (1050/7500) x 100
= 14%
Answer:
both total 3750 so in ratio 1:1 ...so take average of 8 and 20 so it is 14
