When the price of rice rises by 25%, a family can buy 6 kg less rice for ₹1,200. What was the original price of rice per kg?
- ₹50
- ₹32
- ₹45
- ₹40
Answer and explanation
Answer: D. ₹40
Explanation: At the original price p the family gets 1200/p kg; at 1.25p it gets 1200/(1.25p) = 0.8 × 1200/p kg. The 20% drop equals 6 kg, so 1200/p = 30 kg and p = ₹40.
