Detailed Solution

Let the amount paid by Jim, Sashi, and Anuj be x, y, and z. From the given first statement, we get
x+y+z=110   … (1)
Sashi would have eaten equally as his friends the bill would have been equally shared by the three friends which means  x=z  .
Since has to pay half of what Jim paid, we have
y= x 2 x=2y  

Since Sashi also pays half of what Anuj paid, we have
y= z 2 z=2y  
Substitute the above results in the equation (1), we get
2y+y+2y=110 5y=110 y=22  
Hence, the correct option is 2.
