A cement mixture is composed of 3 elements. By weight, 1/5 of the mixture is sand, 3/4 of the mixture is water, and the remaining 6 pounds of the mixture is gravel. What is the weight of the entire mixture in pounds?	Choose the correct choice from the following.
A) 100	B) 120	C) 130	D) 140	E) 150
Let the total weight be x.   Sand content= (1/5)x   Water content= (3/4)x   Gravel=x-(1/5)x-(3/4)x=(1/20)x=6   x=120   Then answer will be 120=120
