If books bought at prices ranging from Rs 200 to Rs 350 are sold at prices ranging from Rs 300 to Rs 425, what is the greatest possible profit that might be made in selling eight books.

Answer: (d)

Least cost price = 200 × 8 = 1600

Greatest sold price = 425 × 8 = 3400

Profit required = 3400 − 1600 = 1800
