such questions do not ask you to precisely calculate the numbers, thereby asking you to rather estimate.
a) \(\frac{143}{17}\) ~some big number
b) \(\frac{48}{9}\) ~ 5+
c) \(\frac{51}{3}\) ~4
d) \(\frac{20}{4}\) ~5
e) \(\frac{16}{3}\) ~5
C is the lowest and is the correct ans.

Question asks to determine lowest ratio of amount disposed / amount recycled.
(A) 142,800 / 16,700 = ~ 8 - 9
(B) 48,000 / 8,800 = ~ 6
(C) 51,400 / 13,000 = ~4
(D) 20,300 / 3,900 = ~ 5
(E) 16,200 / 3,300 = ~ 5
Answer: C.
My advice is before doing calculations estimate the numbers and start with the easiest. No need for exact numerical values, so good approximation will work in this case.
