Working continuously 24 hours a day, a factory bottles Soda Q at a rate of 500 liters per second and Soda V at a rate of 300 liters per second. If twice as many bottles of Soda V as of Soda Q are filled at the factory each day, what is the ratio of the volume of a bottle of Soda Q to a bottle of Soda V?

(A)\(\frac{3}{10}\)
(B)\(\frac{5}{6}\)
(C)\(\frac{6}{5}\)
(D)\(\frac{8}{3}\)
(E)\(\frac{10}{3}\)

From question,
A factory bottles soda Q at the rate of 500 litres every second
or, \(500 * 3600\) litres every hr
or, \(500 * 3600 * 24\) litres every day

Let us assume that every bottle of soda Q is of \(500\) litres.
Hence no of bottles manufactured in the factory = \(\frac{500 * 3600 * 24}{500} = 86400\)

Soda V on the other hand is bottled at the rate of 300 litres every second

Therefore in 1 day total litres filled = \(300 * 24 * 3600\).
We know that the total numbers bottled must be twice the number of Soda Q bottle.
Therefore, we can form a eqn to find the volume of each bottle.

\(\frac{300 * 24 * 3600}{x} = 2 * 86400\)
or, \(3 * 24 * 3600 = 1728x\)
solving for \(x\) we get,
\(x = 150\)
Hence volume of soda Q = 500 while volume of soda V = 150
Ratio = \(\frac{500}{150} = \frac{50}{15} = \frac{10}{3}\)

Explanation

If twice as many bottles of Soda V as of Soda Q are filled at the factory each day, then twice as many bottles of Soda V as of Soda Q are filled at the factory each second.

Use smart numbers for the number of bottles filled each second. Since twice as many bottles of Soda V are produced, the output in one second could be 100 bottles of Soda V and 50 bottles of Soda Q.

Using these numbers, the volume of the Q bottles is 500 liters ÷ 50 bottles = 10 liters per bottle and the volume of the V bottles is 300 liters ÷ 100 bottles = 3 liters per bottle. The ratio of the volume of a bottle of Q to a bottle of V is 10 liters ÷ 3 liters = \(\frac{10}{3}\).

Let the number of bottles be q and v. v = 2q

Volume of a bottle of V = 300/2q
Volume of a bottle of Q = 500/q

Answer = 500/q divided by 300/2q = 10/3
