A borrows an amount of ₹3,600 from B at a rate of 20% simple interest for 2 years and lends 75% of this amount to C at 20% compound interest for 2 years. A uses the remaining amount for his personal purpose. Find the total loss incurred by A.

Rs. 10,000 is being compounded at 20% per annum. Calculate the amount after 2 years if the rate of interest is charged half yearly.

What will be the compound interest on Rs 10000 for 3 years when the rate of interest is 4% in the first year, 5% in the second year and 6% in the third year?

A sum of Rs. 6,000 is deposited for 3 years at 5% per annuam compound interest (compoun- ded annually). The difference of interests for 3 and 2 years will be:

A sum invested at compound inrerest amounts to ₹7,800 in 3 years and ₹11,232 in 5 years. What is the rate per cent? 

If interest be compounded half-yearly, then find the compound interest on ₹8,000 at the rate of 20% per annum for 1 year.
