since its not compounded this is a very simple problem.

r= interest rate

x= principle

y=years

Interest Accumulated = x*y*r

so, in your case:

2500 = 10000 * 5 * r

2500 = 50000r

divide both sides by 2500

and you get: r=.05 (or 5%)

Q: 5 What simple interest rate will Susan need to secure to make 2500 in interest on a 10000 principal over 5 years?

simple interest .. A = P(1+r)t 10000 = P(1.05)5 P = 10000 / (1.05)5 P = 7835.26

To calculate the interest gained on something, a simple formula is used. Initial value x (percentage increase as a decimal)^years So: 10000 x 1.05^15 = 20789.28 (2d.p).

I'll do it both ways since you do not specify whether it is simple of compound interest. FV = P + PRT 10000 = P + P(.03)(20) 10000 = P(1 + 0.60) 10000 = 1.6P 6250 = P Check 6250 * .03 * 20 = 3750 + 6250 = 10000 ◄ FV = P + P(1+R)T 10000 = P + P(1.03)20 10000 = P + P(1.80611) 10000 = 2.80611*P 3563.65 = P Check 3563.25 + 3563.25(1.03)20 3563.25 + 3563.25*1.80611 3563.25 + 6436.35 9999.70 (Rounding error) ◄

The monthly interest is 100.

1000 mcg = 1 mg so 10000 mcg = 10000/1000 = 10 mg. Simple!

Interest = Principal x rate x time 17000= 100000(0.10) t 17000=10000 t t=17000/10000 t=1.7 years

Fixed deposit interest is calculated using the simple interest concept Interest = (principal * no. of years * rate of interest) / 100 principal = the amount you deposited rate of interest = the amount in % Ex: Deposit amount - 10,000 Rate of interest = 10% no of days = 365 Interest = (10000 * 365 * 10) / (365*100) = 1000

Fixed deposit interest is calculated using the simple interest concept Interest = (principal * no. of years * rate of interest) / 100 principal = the amount you deposited rate of interest = the amount in % Ex: Deposit amount - 10,000 Rate of interest = 10% no of days = 365 Interest = (10000 * 365 * 10) / (365*100) = 1000

The formula to calculate interest is as follows: Interest = Principal * No. of years * Rate of Interest / 100 So Interest = 10000 * 0.5 * 8 / 100 = 400/- The interest you will receive interest at the end of the 6 month period is Rs. 400/-

compounding of interest refers to the action wherein, the interest paid to us over a period of time would increase gradually.Ex: Lets say you invest Rs. 10000/- at 10% per annum which is compounded every quarter.So interest for first quarter: Rs. 250/-Principal at the end of first quarter: 10,250/-Interest for second quarter: Rs. 256.25/-Principal at the end of second quarter: 10,506.25/-the increase in interest in the second quarter is because, the interest paid during the first quarter is also considered for interest payment in the second quarter. So, even though the principal amount we invested remains the same the interest varies because of compounding of interest.The shorter the compounding period, greater is the interest earned.Simple interest is to charge interest on the principle amount.compound interest is the interest calculated on the simple interest!

What exactly do you want to calculate? - To calculate the interest amount, you multiply the capital times (interest rate / 100) times the number of periods. In Java, multiplication is expressed by the asterisk.
