Concept: First, find the effective quarterly rate which is r/m, m=no. of quarters in a year which is equal to four. effective quarterly rate= r/m =5/4 =1.25% now, no. of period is equal to n=4 (reason: 4 quarter in a year for which effective rate of 1.25% used) Now, Investment in one year = F= 1,000(F/P, 1.25%, 4) = 1,000(1.0509) = $1050.9
