The ratio is 4:3:1
let the ratio be 4x:3x:x
according to the question,4x+3x+x=40
8x=40
x=5
therefore amount of gravel=x*4=5*4=20

amount of sand=5*3=15

amount of cement=5*1=5
The answer would be H. All you have to do for a problem like this in the future are to add the 3 different angles together and make sure they equal 180 degrees.
