Quantity I: Ravi invested Rs. 35,200 in a plan offering

Solution

Answer: D Quantity I: Amount of money invested by Ravi = Rs. 35,200 Rare of interest compounded = 12.5% Time for investment = 3 years So, the amount of money after 3 years will be, = 35,200 × (1 + 12.5/100)³ = 35,200 × (112.5/100)³ = 35,200 × 112.5/100 × 112.5/100 × 112.5/100 = Rs. 50,118.75 Thus, the amount of interest received by Ravi is, = 50,118.75 –35,200 =>Rs. 14,918.75 Hence, the required answer is = Rs. 14,918.75. Quantity II: Mukul gets an compound interest of = Rs. 8829 Then, according to the question, = 8829 = P [(1 + 18/100)² - 1] = 981P = 8829 × 2500 = P = Rs. 22,500 Now, the total amount of investment is = 22,500 + 4800 =>Rs. 27,300 Then, according to the question, = 27,300 × [(1 + 25/100)² - 1] = 27,300 × 9/16 =>Rs. 15,356.25 Hence, the required answer is = Rs. 15,356.25. Hence, Quantity I < Quantity II.
