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