Production of Three Different Flavours X, Y and Z by a Company over the years (in lakh bottles)

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?

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.

80,000 bottles

C.

240,000 bottles

D.

500,000 bottles

Correct answer is D

Average production of flavour X in 1995, 1996 and 1997

= [ 1/3 x (50 + 40 + 55) ]

= ( 145/3 ) lakh bottles. 

Average production of flavour Y in 1998, 1999 and 2000

= [ 1/3 x (55 + 50 + 55) ]

= ( 160/3 ) lakh bottles.

Therefore Difference = ( 160/3 - 145/3 )

= 15/3

= 5 lakh bottles

= 500,000 bottles.
