Answer» Correct Answer - Option 2 : Rs. 5 Given: Decrease in price = Rs. 0.6/Kg Final purchase - Initial purchase = 1.5 Kg Total amount of apples bought = Rs. 55 Concept: Number of Kg apple bought = (Total money)/(price of 1 kg apple) Calculation: Let, the initial price of apple = Rs. a/Kg Price after reduction = Rs.(a - 0.6)/Kg [55/(a - 0.6)] - (55/a) = 1.5 ⇒ (55a - 55a + 33)/(a2 - 0.6a) = 1.5 ⇒ 33 = 1.5a2 - 0.9a ⇒ 22 = a2 - 0.6a By Values putting from the option; We get a = 5 ∴ The original price of apple per Kg is Rs. 5.
