So, the value of quantity after 1 month,
The value of quantity after 2 months,
From equation (i)
The value of quantity after 3 months,
From equation (ii)
Similarly, the value of quantity after n months,
As 4 years = 48 months, so puttion n=48 to get the value of quantity after 4 years, we have,
Putting Q=6200 and r=5.5%=0.055, we have
Hence, the value of quantity after 4 years is 410.32.
