A boy spends Rs 20 to purchase toffees at Rs 1 each. Next day, he purchased some toffees for Rs 40 with a discount of 50 paise per toffee. What is the average price per toffee (in paise)?
The boy spends Rs 20 to purchase toffees at Rs 1 each, => Number of toffees bought = 20
Toffees purchase next day = $$\frac{40}{0.50}=80$$
Total toffees bought = 100 and amount spent = Rs. 60 = 6000 paise
=> Average price per toffee (in paise) = $$\frac{6000}{100}=60$$
