A person has Rs. 30000 and he invested in four schemes. In 1st scheme he invested 10% of the sum at the rate of 20% per annum, while in 2nd scheme he invested 12% of the amount at the rate of 10% per annum, while in 3rd scheme he invested 25% at the rate of 20% per annum, while in 4th scheme he invested remaining amount at the rate of 25% per annum. After 2 years what is the total amount received by the person. Correct Answer Rs. 42870

Given:

Sum invested in 1st scheme = (10/100) × 30000 = Rs. 3000

Sum invested in 2nd scheme = (12/100) × 30000 = Rs. 3600

Sum invested in 3rd scheme = (25/100) × 30000 = Rs. 7500

Sum invested in 4th scheme = 30000 - (3000 + 3600 + 7500) = Rs. 15900

Formula:

Simple Interest = (Principal × Time × Rate of interest)/100

Amount = Principal + Simple Interest

Calculation:

Interest earned from 1st scheme = (3000 × 20 × 2)/100 = Rs. 1200

Amount received = 3000 + 1200 = Rs. 4200

Interest earned from 2nd scheme = (3600 × 10 × 2)/100 = Rs. 720

Amount received = 3600 + 720 = Rs. 4320

Interest earned from 3rd scheme = (7500 × 20 × 2)/100 = Rs. 3000

Amount received = 7500 + 3000 = Rs. 10500

Interest earned from 4th scheme = (15900 × 25 × 2)/100 = Rs. 7950

Amount received = 15900 + 7950 = Rs. 23850

Total amount received after 2 years from all the schemes

⇒ Rs. 4200 + Rs. 4320 + Rs. 10500 + Rs, 23850 = Rs. 42870

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.

Priya invested her amount at compound interest for ‘x/10’ years at x% 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 ‘x/10’ is a natural number] What is the value of ‘x’? Statement I: Ratio of investment of priya and khushi is 1 : 2 respectively and total sum received by them together after a particular time at x% rate of interest is Rs. 4280.
