For calculation of interest compounded half yearly, keeping the principal same, which one of the following is true?
विकल्प
Double the given annual rate and half the given number of years.
Double the given annual rate as well as the given number of years.
Half the given annual rate as well as the given number of years.
Half the given annual rate and double the given number of years.
उत्तर
Half the given annual rate and double the given number of years.
Explanation:
If interest is compounded half-yearly, then `R = R/2` and T = 2T = 2n
Now, the amount will be
`A = P(1 + R/200)^(2n)`
∴ C = A – P
So, half the given annual rate and double the given number of years.
Hence, half the given annual rate and double the given number of years.
