- A reduction of 20 % in the price of rice enables a person to buy 3.
Question 1:
A reduction of 20 % in the price of rice enables a person to buy 3.5 kg more rice for Rs. 385.The original price of rice is:
A. Rs. 20 per kg
B. Rs. 22.50 per kg
C. Rs. 27.50 per kg
Feedback Let the original price be Rs x per kg.
New price per kg = Rs (80/100 × x) = Rs 4x/5
385/(4x/5) - 385/x = 3.5
=> 1925/4x – 385/x = 7/2
=> (1925 - 1540) = 14x
=> 14x = 385
=> 2x =55
=> x = 27.50
Hence, the original price of the rice is Rs 27.50 per kg
New price per kg = Rs (80/100 × x) = Rs 4x/5
385/(4x/5) - 385/x = 3.5
=> 1925/4x – 385/x = 7/2
=> (1925 - 1540) = 14x
=> 14x = 385
=> 2x =55
=> x = 27.50
Hence, the original price of the rice is Rs 27.50 per kg
D. Rs. 25 per kg
