Karan, Nishant and Vignesh start on a trip with Rs.5000 each and agree to share the expenses equally. If at the end of the trip, Karan has Rs.200 left with him, Nishant has Rs.300 left with him and Vignesh Rs.400, how much should Vignesh pay to Karan, considering all the expenses should be shared equally?
Rs.100
Total money for the trip =Rs.15000
Money spent by Karan =Rs.4800
Money spent by Nishant = Rs.4700
Money spent by Vignesh = Rs.4600
Total money spent = Rs.14100
Expenses per head = Rs.4700
So the money that Vignesh has to pay to Karan is Rs.100.
