N1.50

N7.50

N15.00

N18.00

Answer Details

I = N 4.50, P = N 150, T = 2 \frac{1}{2} y e a r s I = \frac{P \times T \times R}{100} 4.50 = \frac{150 \times 2 \frac{1}{2} \times R}{100} \frac{4.50}{1} = \frac{150 \times 5 \times R}{100 \times 2} 4.50 \times 4 = 15 R R = \frac{4.50 \times 5}{15} R = \frac{6}{5} A g a i n I = \frac{P \times T \times R}{100} = \frac{250 \times 1 \times 6}{100 \times 2 \times 5} = \frac{3}{2} = N 1.50
