A company produced a new energy drink of three different flavours - P, Q and R - for athletes. The production of the three flavours over a period of six years from 2001 to 2006 has been expressed in the bar graph shown below. Study the graph and answer the question that follows.    For which of the following years is the percentage increase/ decrease in production from the previous year the highest for flavour R?

A company produced a new energy drink of three different flavours - P, Q and R - for athletes. The production of the three flavours over a period of six years from 2001 to 2006 has been expressed in the bar graph shown below. Study the graph and answer the question that follows.    For which of the following years is the percentage increase/ decrease in production from the previous year the highest for flavour R? Correct Answer 2005, decrease 

Calculation:

The production of energy drink in the year 2001 by R = 450

The production of energy drink in the year 2002 by R = 500

The percentage increase =

⇒ (50/450 × 100)

⇒ 11.11% increase

The production of energy drink in the year 2002 by R = 500

The production of energy drink in the year 2003 by R = 600

The percentage increase =

⇒ (100/500 × 100)

⇒ 20% increase

The production of energy drink in the year 2003 by R = 600

The production of energy drink in the year 2004 by R = 600

The percentage increase =

⇒ (0/600 × 100)

⇒ 0

The production of energy drink in the year 2004 by R = 600

The production of energy drink in the year 2005 by R = 450

The percentage decrease =

⇒ (150/600 × 100)

⇒ 25% decrease

The production of energy drink in the year 2005 by R = 450

The production of energy drink in the year 2006 by R = 400

The percentage decrease =

⇒ (50/450 × 100)

⇒ 11.11% decrease

∴ The percentage increase/ decrease in production from the previous year the highest for flavour R is 2005, decrease
