A man invested a sum of Rs. 25,000. He invested some part at 5% p.a. and remaining at 5.5% p.a.

How much money did he invest at 5% p.a.?

Statement I : The total interest amount paid after 1 year was Rs. 2230.

Statement II : The interest on one sum was twice that on the other.

A If the data in statement I alone is sufficient to answer the question. Correct Answer Incorrect Answer
B If the data in statement II alone is sufficient to answer the question. Correct Answer Incorrect Answer
C If the data either in statement I alone or statement II alone are sufficient to answer the question. Correct Answer Incorrect Answer
D If the data given in both I and II together are not sufficient to answer the question. Correct Answer Incorrect Answer
E If the data in both the statements I and II together are necessary to answer the question. Correct Answer Incorrect Answer

Solution

Let first part is Rs x, then remaining is Rs (25000 - x) From statement I ((x * 5 * 1)/100) + ((25000 - x) * 5.5 * 1/100) = 2230 So, "x" can be calculated. From statement II , ((x * 5 * 1)/100) = 2 * ((25000 - x) * 5.5 * 1/100) So, "x" can be calculated.
