If P is the principal, R is the rate of interest per annum and n is the time period, find the amount at the end of the nth year if the interest is compounded yearly.

The simple interest on a sum of money is (4)/(9) times the principal and the rate of interest per annum is numerically equal to the number of years. Find the rate of interest per annum.

If P=Rs. 6000 and R=5% per annum, find the amount in 1 year interest compounded half yearly.

Mr. Duggal invested 20000 with rate of interest "@" 20% per annum. The interest was compounded half-yearly for the first 1year and in the next year it was compounded yearly. What will be the total interest earned at the end of 2 years?

Formula 1 Let P be the principal and the rate of interest be R% per annum.If the interest is compunded anually then the amount A and the compound interest C.I.at the end of n years are given by nA=P(1+(R)/(100))^(n) and C.I.=A-P=P{(1+(R)/(100))^(n)-1} respectively.

Formula 2 Let P be the principal and the rate of interest be R% per annum.If the interest is compounded annually then the amount A and the compound interest C.I.at the end of n years are given by A=P(1+(R)/(100k))^(nk) and C.I.A-P=P{((1_(R))/(100k))^(nk)-1} respectively

If the rate of interest is 10% per annum and is compound half-yearly. then the principle of ₹400 in 3/2 years will amount to
