Option(D) is correct

Average production of flavour $X$ in 1995, 1996 and 1997:

$= \left[\dfrac{1}{3} × (50 + 40 + 55)\right]$

$=\dfrac{145}{3}$ lakh bottles.

Average production of flavour Y in 1998, 1999 and 2000:

$=\left[\dfrac{1}{3} × (55 + 50 + 55)\right]$

$=\dfrac{160}{3}$ lakh bottles.

⇒ Difference $=\left[\dfrac{160}{3} – \dfrac{145}{3}\right]$


= 5 lakh bottles

= 5,00,000 bottles

I dont think the unit had been mentioned anywhere in the chart or the sum. This makes the answer confusing.


Thank you for pointing it out, modified the question.
