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 %)?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 14
Cheese tin cost = 750
Discount = 8%
Discounted price = (92/100) × 750 = 690
Cost of 5 cheese tins = 3450 eq1
Butter tin cost = 1250
Discount = 20%
Discounted price = 1250 × (80/100) = 1000
Cost of 3 butter tins = 3000 eq2
Total cost = 6450
Total cost without discount = 7500
% = (6450 / 7500) × 100 = 86%
Discount percent = 14%
