Given : Tejas has as many Rs 50 notes as darshan has Rs 100 notes

and Tejas has as many Rs 100 notes as darshan has Rs 50 notes

Tejas has Rs 1000 in total

Darshan has Rs 1100 in total

To Find : How many Rs 50 notes Darshan has

Solution:

                    Tejas      Darshan    

Rs 50              x              y

Rs 100             y               x

              50x + 100y      50y + 100x

               1000                 1100

 50x + 100y  = 1000

=> x + 2y  = 20

50y + 100x  = 1100

=> y  + 2x  = 22

x + 2y  = 20

y  + 2x  = 22

=>  3y =  18   => y  = 6     and x  = 8
