Answer» LET the ORIGINAL price of the rice per kilograms = Rs. x. The price of rice is REDUCED by 25%. After reduction, the price of rice per kilograms = Rs. x × (75/100) = Rs. 3x/4 Now we can write, 54/(3x/4) = (54/x) + 0.750 ⇒ (216/3x) – (54/x) = 0.750 ⇒ 216 – 162 = 2.25x ⇒ x = 54/2.25 ⇒ x = 24 ∴ The original price of the rice per kilograms = Rs. 24 |
