For Company A,
The amount received by Samir in 2008 $=10000\left(1+\frac{11.5}{100}\right)\left(1+\frac{15}{100}\right)$
$=10000\times \frac{223}{200}\times \frac{23}{30}$ = Rs. 12822.50
Hence, their interest = 12822.50 – 10000 = Rs. 2822.50
For Company B,
The amount received by Samir in 2008 $=10000\left(1+\frac{13.5}{100}\right)\left(1+\frac{14}{100}\right)$
$=10000\times \frac{227}{200}\times \frac{57}{50}$ = Rs. 12939
Since, their interest = 12939 – 10000 = Rs. 2939Hence, difference between the interests earned = 2939 – 2822.50 = Rs. 116.50
If Samir had invested the amount in company B for both years then he would get Rs. 116.50 more.
