A sum of Rs. 5000 becomes Rs. 8000 in 3 years when invested in a scheme of simple interest. If the same sum is invested in a scheme of compound interest with the same yearly interest rate (compounding of interest is yearly), what will be the amount (in Rs.) after 3 years?

A sum of Rs. 5000 becomes Rs. 8000 in 3 years when invested in a scheme of simple interest. If the same sum is invested in a scheme of compound interest with the same yearly interest rate (compounding of interest is yearly), what will be the amount (in Rs.) after 3 years? Correct Answer 8640

S.I = Amount – Principal = 8000 – 5000 = 3000

S.I. = (P × R × T)/100

⇒ 3000 = (5000 × R × 3)/100

⇒ R = 1000/50 = 20% = 1/5

∴ Amount after 3 years (at C.I.) = 5000 × 6/5 × 6/5 × 6/5 = 8640

Each of the questions below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Priya and khushi invested Rs.3000 together. Priya invested her amount at compound interest for ‘v/10’ years at v% rate interest and khushi invested half of her amount at compound interest and remaining half at simple interest at the same rate of interest for the same time period. [It is given that ‘v/10’ is a natural number] What amount is received by Khushi after ‘v/10’ years? Statement I: Value of ‘v’ can be determined by the equation : 3v2 – 55v - 100 = 0. Statement II: Priya invested Rs. 1000 less than amount invested by Khushi. Statement III: Total sum received Priya and Khushi together after ‘v/10’ years is Rs. 4280.
