A sum is invested at 10 % per annum with simple interest. What will be the time taken to increase its value by 25% ?

The difference between compound interest and simple interest on a sum for 2 years at 20% per annum, when the interest is compounded annually is ₹32. If the interest were compounded half-yearly, the difference in two interests would be:

A sum of ₹ 5500 is lent out in two parts in such a way that the interest on one part at 12% for 4 years is equal to that on another part at 8% for 5 years. What will be the two parts of the sum?

The simple interest of an amount is $\frac{16}{25}$ of the principal. Find the rate % PA, if the time and rate both are numerically equal.

Consider the compound interest of the following

(A) The compound interest on Rs 16000 at 20% per annum for 9 months, compounded quarterly is: Rs 2522

(B) The compound interest on Rs 2800 at 10% per annum for 18 months, compounded annually is: Rs 434

Choose the correct statement(s):

Consider the compound interest of the following

(A) The compound interest on Rs 30500 at 15% per annum for 2 years, (compounded annually) is: Rs. 9836.25

(B) The compound interest of Rs 5000 at 20% per annum for one year is compounded (half-yearly) is: Rs. 6050.

Which of the following statements is / are correct?

If the interest is payable annually, then the principal amount on which the compound interest for 2 years at 5% per annum is ₹ 369, is given by
