What number is that, to which, if its half be added, and from the sum 20 be subtracted, the remainder will be a fourth of the number itself?	Choose one.
A) 16/3
B) 16/2
C) 16/4
D) 16/1
E) None
let x be put for the number required.   Then by the conditions proposed, x + x/2 - 20 = x/4   And reducing the equation x = 16.   Proof, 16 + 16/2 - 20 = 16/4.   Answer 16/4
