Go by this formula 2r+r^2÷100.
That is 2(5) + 25÷100.
Then you will get 10.25,
Now you go for cross multiplication.
For 100 --8000
110.25--?
Your answer will be=8820
Thank you friends.

Another formula for compound CI=p(1+r/n)^nt.
Any body know what is n means in this formula?

Given: r = 5, n = 2, p = 8000.
Amount = P[1+r/100]^n;
CI = Amount + principal;
Amount = P[1+r/100]^n;
CI = Amount + principal;

I will use this formula: FV = PV(1+r)^t.
FV = the future value that Albert will received, PV= is the amount he is investing currently; r= rate and t = number of years the investment will last.
Now let go back to the question: PV= Rs.8000, r=5%=5/100=0.05, t=2years, FV is what we are to solve.
FV = PV(1+r)^t.
8000(1+0.05)^2.
8000(1.05)^2.
Find the square of 1.05 = 1.05*1.05 or 1.05^2 = 1.1025.
Therefore, FV = 8000*1.1025 = Rs.8820.

@Shivani.
C.I = P(1 +R/100)^n.
Use this formula you will get answer.
C.I = P(1 +R/100)^n.
Use this formula you will get answer.

Hi @Suraj its formula for compound interest = p(1+r/100)^n where r is rate 5% and n is time which is already mentioned in question.
