Question

A shopkeeper bought 200 books at ₹30 each. He sold 150 of those at ₹25 each. What is the price he should sell the remaining books at, to have neither profit nor loss?

• A. ₹40
• B. ₹45
• C. ₹50
• D. ₹55

Answer 1

The correct option is B ₹45

Money spent on buying 200 books
$=200\times 30=₹6000$

Money received on selling 150 books
$=150\times 25=₹3750$

Selling price of remaining 50 books to have neither profit nor loss
$=\frac{6000-3750}{50}=\frac{2250}{50}=₹45$
