Let the number of 2 rupee coin be x
So, 5 rupee coins are (165-x)
So, 2x + 5(165-x)=555
2x + 825-5x = 555
2x - 5x = 555-825
-3x = - 270
X=-270/-3
X=90
So,number of 2 rupee coin = 90 and
Number of 5 rupees coins = (165-90)=75
So, 5 rupee coins are (165-x)
So, 2x + 5(165-x)=555
2x + 825-5x = 555
2x - 5x = 555-825
-3x = - 270
X=-270/-3
X=90
So,number of 2 rupee coin = 90 and
Number of 5 rupees coins = (165-90)=75
