Answer» Correct Answer - Option 2 : Rs. 11.67 and Rs. 14.58 Given: Due to a reduction of 20% in the price of potato, Amit can purchase 6 kg more for Rs. 350. Formula used: Percentage = (value/total value) × 100 Calculation: Due to 20% reduction in price Amit can Purchase 6 kg more ⇒ 20% = 6 kg ⇒ 100% = (6/20) × 100 = 30 kg Now the total weight of Potato is 30 kg Reduced price of 1 kg Potato = Rs. (350 / 30) = Rs. 11.67 Previous price of 1 kg Potato = Rs. (350 / 24) = Rs. 14.58 ∴ Reduced and the previous price of 1 kg Potato are Rs. 11.67 and Rs. 14.58 respectively. Shortcut Trick: 6 kg = 350 ⇒ 1 kg = 350 / 6 Reduced price = Rs. {(350 / 6) × (20 / 100)} = Rs. 11.67 Previous price = Rs. {11.67 / (80 / 100)} = Rs. 14.58 ∴ Reduced and the previous price of 1 kg Potato are Rs. 11.67 and Rs. 14.58 respectively. |
