As a result of a 25% hike in the price of rice per kg, a person is able to purchase 6 kg less rice for Rs. 1,200. What was the original price of rice per kg?
- A.Rs. 30
- B.Rs. 40
- C.Rs. 50
- D.Rs. 60
▶ Answer & Explanation
Correct answer: B. Rs. 40
A 25% increase in price means the new price is 1.25 times the original price. If the total expenditure remains the same (Rs. 1,200), a price hike necessitates a reduction in the quantity purchased. The difference in quantity (6 kg) for the same amount of money highlights the impact of the price increase. By setting up an equation based on the original and new prices and quantities, one can solve for the original price.
