The bar chart given below shows the sales of 3 types of cars in the Indian automotive industry over 4 years. All the sales figures have been shown in terms of '000 units.
If all the 3 categories increase by same rate in 2013 over 2012 as they did in 2012 over 2011, then what will be the total approximate sales (in ‘000 units) of all the 3 categories taken together in year 2013 ?
Rate of increase of Hatchback from 2011 to 2012 = $$\frac{(800-650)}{650}\times100\approx23\%$$
=> Sales of Hatchback in 2013 (in '000 units) = $$\frac{(100+23)}{100}\times800=984$$
Similarly, rate of increase of Sedan from 2011 to 2012 = $$\frac{(625-575)}{575}\times100\approx9\%$$
=> Sales of Sedan in 2013 (in '000 units) = $$\frac{(100+9)}{100}\times625=680$$
Rate of increase of SUV from 2011 to 2012 = $$\frac{(750-400)}{400}\times100\approx87.5\%$$
=> Sales of SUV in 2013 (in '000 units) = $$\frac{(100+87.5)}{100}\times750=1406$$
$$\therefore$$ Total approximate sales (in ‘000 units) of all the 3 categories taken together in year 2013
= $$984+680+1406=3070\approx3069$$
