Answer : 1. "Rs. 6000"
Explanation :

Answer: A) Rs. 6000 Explanation: Let the sum invested be Rs. P Let the rate of interest be R% per annum => Interest earned for 5 years = (P x 5 x R/100) = PR/20 Now, given that the interest earned increased by Rs. 600 if the Rate increased to (R+2)% => SI = (P x 5 x (R+2))/100 = PR/20 + 10P/100 Hence, PR/20 + 10P/100 = PR/20 + 600 => P = 6000 Therefore, the sum invested is Rs. 6000

Answer :
Explanation :

In most cases, you will have no idea who you are competing with for a particular job. So this type of question really gives you a chance to open-up your strengths as a candidate with an emphasis on any assets that might separate you from the typical applicant. Think about what you bring to the table that you truly believe is unique - the easiest way to do is to think of your own personal stories that demonstrate your work ethic, skills, and dedication. Most people have some or all of those skills, but the unique stories are what make people stand out in interviews.

Answer : 3. "Rs. 9000"
Explanation :

Answer: C) Rs. 9000 Explanation: Let Rs. K invested in each scheme Two years C.I on 20% = 20 + 20 + 20x20/100 = 44% Two years C.I on 15% = 15 + 15 + 15x15/100 = 32.25% Now, (P x 44/100) - (P x 32.25/100) = 528.75 => 11.75 P = 52875 => P = Rs. 4500   Hence, total invested money = P + P = 4500 + 4500 = Rs. 9000.
