Amount in the beginning = Rs. 10000

Interest at the end of 1st year at rate of \small 8\hspace{1mm}\%
is \small 8\hspace{1mm}\% of 10000 = \frac{8\times 10000}{100}= 800

Therefore, amount at the end of 1st year will be

= 10000 + 800

= 10800

Now,

Interest at the end of 2nd year at rate of \small 8\hspace{1mm}\%
is  \small 8\hspace{1mm}\% of 10800 =\frac{8\times 10800}{100}= 864

Therefore,, amount at the end of 2ndyear

= 10800 + 864 = 11664
