Solve these two equations for x and y:

x + y = 50

x + 2y = 75

(y is the number of 2 rupee coins; x is the number of 1 rupee coins)

Clearly y = 25, and x is also 25.

he has 25 one rupee coins and 25 two rupee coins together he has 50 coins with total amount of 75 rupees

1*25+2*25=25+50=75 rupees
