Explanations
1. The percentage increases are:
In 2008: (450 – 240)/240 * 100 = 87.5%
In 2009: (750 – 450)/450 * 100 = 66.6%
In 2010: (660 – 750)/750 * 100 = -12%
In 2011: (1050 – 660)/660 * 100 = 59.1%
2. The percentage changes in raw materials are:
In 2008: (450 – 240)/240 * 100 = 87.5%
In 2009: (750 – 450)/450 * 100 = 66.6%
In 2010: (660 – 750)/750 * 100 = -12%
In 2011: (1050 – 660)/660 * 100 = 59.1%
The percentage changes in finished goods are:
In 2008: (600 – 400)/400 * 100 = 50%
In 2009: (1000 – 600)/600 * 100 = 66.6%
In 2010: (800 – 1000)/1000 * 100 = -20%
In 2011: (1200 – 800)/800 * 100 = 50%
3. The total expenditure on raw materials = 240 + 450 + 750 + 660 + 1050 + 840 = 3990 lakhs
The total value of the finished goods = 400 + 600 + 1000 + 800 + 1200 + 920 = 4920 lakhs
The total profit = 930 lakhs. The avg profit = 930/6 = 155 lakhs.
4. Profit each year:
In 2007: (400 – 240) = 160 lakhs
In 2008: (600 – 450) = 150 lakhs
In 2009: (1000 – 750 ) = 250 lakhs
In 2010: (800 – 660) = 140 laks
In 2011: (1200 – 1050) = 150 lakhs
In 2012: (920 – 840) = 80 lakhs
5. The percentage changes in profit are:
In 2008: (150 – 160)/160 * 100 = -6.2%
In 2009: (250 – 150)/150 * 100 = 66.6%
In 2010: (140 – 250)/250 * 100 = -44%
In 2011: (150 – 140)/140 * 100 = 7.1%
