Let the number of carrots = x
Let the number of Brussel sprouts = y
Let the number of celery sticks = z
Now, we want to find the ratio of carrots to the number of celery sticks.
i.e what is x:z?
Statement 1: The number of carrots is 8/15 the number of Brussel sprouts.
x = 8/15 of y = 8y / 15
x:z = 8y/15 : z
The value of z is unknown, hence, statement 1 is NOT SUFFICIENT.

Statement 2: The number of Brussel sprouts is three times the number of celery sticks.
y = 3 * z
z = y/3
Since the value of x is unknown, statement 2 is, therefore, NOT SUFFICIENT.

Combining both statements together:
From statement 1: x = 8y/15
From statement 2: z = y/3
$$x:z\ =\ \frac{x}{z}=\frac{\frac{8y}{15}}{\frac{y}{3}}$$
$$=\frac{8y}{15}\cdot\frac{3}{y}=\frac{8}{5}$$
x : z = 8 : 5.
Therefore, both statements combined together ARE SUFFICIENT.

Answer = option C
