50,000 bottles
80,000 bottles
240,000 bottles
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.
