Study the following graph carefully to answer the questions.
Percent Profit Earned by Two Companies Producing Electronic Goods over the Years
percent profit =$$\frac{Profit Earned}{Total Investment}\times100$$
Profit Earned = Total Income - Total Investment in the year
If the incomes of Company A in 2007 and 2008 were equal and the amount invested in 2007 was Rs. 12 lakhs, what was the amount invested in 2008?
Income = Profit earned + Investment
Since income in 2007 = income in 2008,
Profit (2007) + Investment (2007) = Profit (2008) + Investment(2008)
Profit = Investment * Percent profit/100
So, 12 lakhs (.45) + 12 lakhs = Investment(2008) * .6 + Investment(2008)
So, Investment(2008) = 10.875 lakhs
