Question

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

• A. 50,000 bottles
• B. 2,40,000 bottles
• C. 3,30,000 bottles
• D. 5,00,000 bottles

Answer 1

The correct option is D

5,00,000 bottles

Average production of flavour X in 1995, 1996 and 1997 = $\left[\frac{1}{3}\times \left(50+40+55\right)\right]$ $=\left(\frac{145}{3}\right)lakhbottles.$

Average production of flavour Y in 1998, 1999 and 2000 = $\left[\frac{1}{3}\times \left(55+50+55\right)\right]$ $=\left(\frac{160}{3}\right)lakhbottles.$

$\therefore$ Difference = $\left(\frac{160}{3}-\frac{145}{3}\right)=\frac{15}{3}=5$ lakh bottles = 5,00,000 bottles.
