Question

Q. Due to a reduction of 21% in the price of rice, a man is able to purchase 3 kg extra for Rs. 300 as before. Find out the reduced price per kg?

• A. Rs. 20 per kg
• B. Rs. 18 per kg
• C. Rs. 21 per kg
• D. Rs. 28 per kg

Answer 1

The correct option is C Rs. 21 per kg

Explanation:

If the price of rice is reduced by 21%, the same quantity of rice which was available for Rs. 300 earlier is now available for Rs. 237.

If today we are paying Rs. 300 means we are paying Rs. 63 extra and for these Rs. 63 we are getting 3 kg rice extra.

Reduced price

3 kg rice = Rs. 63

1 kg rice $=\frac{63}{3}=Rs.21$ per kg.
