The principal that amounts to Rs.4913 in 3 years at per annum compound interest compounded annually, is :

If the compound interest on a sum for 2 years atper annum is Rs.510, the simple interest on the same sum at the same rate for the same period of time is :

The simple interest on a certain sum of money for 3 years at 8% per annum is half the compound interest on Rs.4000 for 2 years at 10% per annum. The sum placed on simple interest is :

The difference between simple and compound interests compounded annually on a certain sum of money for 2 years at 4% per annum is Rs.1. the sum (in Rs.) is:

The effective annual rate of interest corresponding to a nominal rate of 6% per annum payable compounded half-yearly is :

Simple interest on a certain amount is of the principle. If the numbers representing the rate of interest in present and time in years be equal, then time, for which the principle is lent out, is:

A lends Rs.2500 to B and a certain sum to C at the same time at 7% p.a. simple interest. If after 4 years, A altogether receive Rs.1120 as interest from B and C, then the sum lent to C is :

If the simple interest on a certain sum for 15 months at % per annum exceeds the simple interest on the same sum for 8 months at  per annum by Rs.32.50, then the sum (in Rs.) is :

A man invests a certain sum of money at 6% p.a. simple interest and another sun at 7% p.a. simple interest. His income from interest after 2 years was Rs.354. One-fourth of the first sum is equal to one-fifth of the second sum. The total sum invested was:

A borrowed 830 from B at 12% p.a. S.I. for 3 years. He then added some more money to the borrowed sum and lent it to C for the same period at 14% p.a. rate of interest. If A gains Rs.93.90 in the whole transaction, how much money did he add from his side?
