If the amount of profit earned by Company B in the year 2007 was Rs. 7.56 lakhs, what was the profit earned by it in the year 2005?

Solution

Let the profit earned by company B in the year 2005 = $$Rs. x$$

% increase in profit of company B in 2006 = 35 %

% increase in profit of company B in 2006 = 45 %

=> $$x \times \frac{135}{100} \times \frac{145}{100} = 7.56$$

=> $$x = \frac{7.56 \times 100 \times 100}{135 \times145}$$

=> $$x = 3.86$$ lakhs
