If 4250 naira is invested at 3¾ per annum. What is half the interest yearly

Answer 1

The interest yearly can be calculated as:

I = P * r

where I is the interest, P is the principal (the amount invested), and r is the interest rate as a decimal. Converting 3¾ to a decimal gives 0.0375.

So, for an investment of 4250 naira:

I = 4250 * 0.0375
I = 159.375 naira

Half of the interest yearly would be:

159.375 / 2 = 79.69 naira (rounded to two decimal places)
