Question

what is formula of compound half yearly?​

Answer 1

CI = A - P = P{(1 + r2100)2n - 1}

Answer 2

Answer:

the principal = P, rate of interest per unit time = r2%, number of units of time = 2n, the amount = A and the compound interest = CI

Then

A = P(1 + r2100)2n

Here, the rate percent is divided by 2 and the number of years is multiplied by 2

Therefore, CI = A - P = P{(1 + r2100)2n - 1}

Step-by-step explanation:

Note:

A = P(1 + r2100)2n is the relation among the four quantities P, r, n and A.

Given any three of these, the fourth can be found from this formula.

CI = A - P = P{(1 + r2100)2n - 1} is the relation among the four quantities P, r, n and CI.
