Let the number of prizes of money 100 be x, and the number of prizes of cost 25 be y ;
x+y = 63
y = 63-x -------(1)
100x+25y = 3000
4x+y = 120
y = 120-4x ------(2)
63-x = 120-4x
4x-x = 120-63
3x = 57
x = 19
y = 63-x = 63-19
y = 44
Hence the number of prizes of cost 100 each are 19 while other type of prizes are 44
x+y = 63
y = 63-x -------(1)
100x+25y = 3000
4x+y = 120
y = 120-4x ------(2)
63-x = 120-4x
4x-x = 120-63
3x = 57
x = 19
y = 63-x = 63-19
y = 44
Hence the number of prizes of cost 100 each are 19 while other type of prizes are 44
