Download Solution PDFGiven:
As a result of 25% hike in the price of rice per kg, a person is unable to purchase 6 kg more rice for ₹ 1,200.
Formula used:
Let the original price of rice be ₹x per kg.
After a 25% hike, the new price = ₹x + 0.25x = ₹1.25x per kg.
Amount of rice bought originally = 1200/x kg
Amount of rice bought after hike = 1200/1.25x kg
Difference in quantity = 6 kg
Calculation:
1200/x - 1200/1.25x = 6
⇒ 1200/x - 960/x = 6
⇒ 240/x = 6
⇒ x = 240/6
⇒ x = ₹40
∴ The correct answer is option 3.
