If a reduction of 10% in the price of rice enables a person to obtain 22 kg more for Rs. 250, then the original price of rice per kg is ________.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. Rs. 1.26.
Let the original price per kg = x
(250/0.9x) - (250/x) = 22
⇒ 250/9x = 22
⇒ x = 250/(9 × 22) ≈ 1.26
