Question Detail

A soft drink company prepares drinks of three different flavours X, Y and Z. The production of the three flavours over a period of six years has been expressed in the form of bar graph below. Study the bar graph and answer the question based on graph.

What is the difference between the average production of flavour X in 1995, 1996 and 1997 and the average production of the flavour Y in 1998, 1999 and 2000 ?

50,000 bottels
55,000 bottels
1,000,00 bottels
1,100,00 bottels

Answer: Option C

Explanation:

Average production of flavour X in 1995, 1996 and 1998 is
\begin{aligned}
\left[ \frac{1}{3}*(50+40+55) \right] \\
= \frac{145}{3} \text{lakh bottels} \\
\end{aligned}

Average production of flavour Y in 1998, 1999 and 2000 is
\begin{aligned}
\left[ \frac{1}{3}*(55+50+55) \right] \\
= \frac{160}{3} \text{lakh bottels} \\
Difference = \frac{160}{3} - \frac{145}{3} \\
= \frac{15}{3} = 5 \\
\end{aligned}

So it will be 5 lakh bottels, which is 500000 bottels
