Assuming simple interest, the formula is Interest = Principal x Time x Rate/100, in this case the interest would be 30% of the original investment.
If the interest is compounded yearly the the formula is Principal x (1 + Rate/100)^Time so that the new total would be (1 + 0.1)^3 ie 1.331 times the original investment, a total of 33.1% interest.
It depends on whether the 4% interest is per annum or for 8 years altogether. Also, you have to see if it is a simple interest or compounded interest.

If the 3% is "simple" interest, then the $100 earns an extra $18 in 6 years. If the interest is compounded yearly, then it earns $19.41 extra. If the interest is compounded weekly, then it earns $19.72 extra.
simple interst is when you earn interest from your principal but compound interest is when you earn interest from your principal as well as from your previous interest
If interest is 2.75% per annum and is compounded quarterly, then aninitial investment of $2,000 will amount to $2,630.58after 10 years.
$494.34 Interest= principal amount * time* simple interest %
To calculate the total amount after 10 years at a simple interest rate of 20% per annum, you need to consider that the interest is added to the principal each year. The sum will be multiplied by 1.2 (100% + 20%) each year for 10 years. Therefore, the sum will be multiplied 10 times over the course of 10 years.

Assuming simple interest, you multiply the capital times the interest rate times the number of years.

Oh, what a lovely question we have here! To find the time it takes for 2700 to yield the same interest as 2250 in 4 years, we simply need to compare the interest rates. Since the interest rates are different, we can use a formula called the "interest formula" to solve for the time needed. Let's embrace the joy of solving this together!
If the 3% is "simple" interest, then the $100 earns an extra $18 in 6 years. If the interest is compounded yearly, then it earns $19.41 extra. If the interest is compounded weekly, then it earns $19.72 extra.
I believe an annum is one year. (ie; $50,000 per annum - per year)
