Amount=_____________+ Interest.

Amount by compound interest = ............ xx (1 + (Rate)/100 ) ^(Time) , the blank space covers by:

An amount is invested in a bank at compound rate of interest . The total amount, including interest, after first and third year is X 1200 and X 1587 , respecitvely. What is the rate of interest ?

Demonstrate that doubling the time while halving the interest rate results in the same amount of simple interest.

On an amount simple interest of 1.5 years at 8% per annum is Rs. 420 . find the principle.

'On certain amount simple interest is 16/25 th part of the amount taken then the time and rate of interest is_____ (Numerically same)

Rs. 5000 is deposited at 6% simple interest. Check, if the interest amount at the end of every year is in A.P. then find the amount of interest after 10 years.

If the ratio of the principal and amount (principal + interest) is 20 : 21, then the rate of interest per annum is

Rs. 1000 is deposited at 10 per cent simple interest. Check if the interest amount at the end of every year is in A.P. If this is A.P. then find amount of the interest after 20 years. For this complete the following activity.
