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%
