A firm producing air purifiers sold 200 units in 2012. The following pie chart presents the share of raw material, labour, energy, plant & machinery, and transportation costs in the total manufacturing cost of the firm in 2012. The expenditure on labour in 2012 is Rs. 4,50,000. In 2013, the raw material expenses increased by 30% and all other expenses increased by 20%. What is the percentage increase in total cost for the company in 2013?

For 2012,

Labour: 450000; Raw Material: 600000; Energy: 750000; Machinery: 900000; Trans: 300000; Total : 30,00,000

For 2013,

Labour: 540000; Raw Material: 780000; Energy: 900000; Machinery: 1080000; Trans: 360000; Total : 36,60,000

Therefore, percentage increase in total cost is { (Total cost(2013) - Total cost(2012)) / Total cost(2012) } * 100 = 22%
