If 45% of z is 120% of y and y is 75% of x, what percent of x is z?
Pick one
A) 200
B) 160
C) 100
D) 65
E) 50
(45/100)z = (120/100)y   and y = (75/100)x i.e. y = (3/4)x   i.e. (45/100)z = (120/100)*(3/4)x   i.e. z = (120*3)x/(45*4)   i.e. z = (2)x = (200/100)x   i.e. z is 200% of x   200nswer: Option 200
