A reduction of 20% in the price of wheat enables a person to buy 3.5 kg more wheat for ₹ 770. The original price of rice is?
Correct Answer: ₹ 55 per kg
Explanation:
Here, R = 20%, A = 3.5 kg and P = ₹ 770
According to the formula ,
Actual price of rice = [PR /(100 - R)] A
= [(20 x 770) / (100 - 20)] x 3.5
= [(20 x 770) / (80 x 3.5)
= ₹ 55
