A reduction of 20% in the price of sugar enables a person to buy 5 kg more for Rs. 200. What is the original price per kg?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Rs. 10.
Let original price = p per kg, Quantity bought = 200/p kg
New price = 0.8p, Quantity = 200/(0.8p) = 250/p kg
Difference = 250/p – 200/p = 50/p = 5
⇒ p = Rs. 10 per kg
