If N225.00 yields N27.00 in x years simple interest at the rate of 4% per annum, find x.

If N225.00 yields N27.00 in x years simple interest at the rate of 4% per annum, find x. 

Answer Details

Principal = N225.00, interest = N27.00

Year = x, Rate = 4% 

1 = PRT100 $\frac{PRT}{100}$

27 = 225×4×x100 $\frac{225\times 4\times x}{100}$ = 2700 = 900T

T = 2700900 $\frac{2700}{900}$ 

= 3 years
