A cement mixture is composed of 3 elements. By weight, 1/4 of the mixture is sand, 2/5 of the mixture is water, and the remaining 14 pounds of the mixture is gravel. What is the weight of the entire mixture in pounds?	Choose the correct option
A) 9 B) 14 C) 28 D) 40 E) 60
Let the total weight be x.   Sand content= (1/4)x   Water content= (2/5)x   Gravel=x-(1/4)x-(2/5)x=(7/20)x=14   x=40   Then answer will be 40=40
