in x game of billiards , x can give y 20 points in 45 and he can give z 30 points in 45 . how many points can y give z in x game of 100 ?
"x scores 45 while y score 40 and z scores 30 . the number of points that z scores when y scores 100 = ( 100 * 30 ) / 25 = 60 . in x game of 100 points , y gives ( 100 - 60 ) = 40 points to c . d"
subtract(multiply(subtract(45, 20), const_3), multiply(subtract(45, 30), const_3))
