Difference in C.I. and S.I. for 2 years = Rs. 32
S.I. for one years = Rs. 400
`:.` S.I. on Rs. 400 for one year = Rs. 32
So, Rate = ` ((100 xx 32)/(400 xx 1))`% = 8%
Hence , difference in C.I. and S.I. for 3rd year
= S.I. on Rs. 832 = Rs. `((832 xx 8 xx 1)/(100))` = Rs. 66.56.
Total difference = Rs. (32 + 66.56) = Rs. 98.56
