Question 97

# What is the approximate proportion of coal in the domestic consumption of energy in 2012?

Solution

Consumption of energy in the given country for the year 2012 is as follows:

540(1.15)(1.1)(1.15) + 290(1.1)(1.1)(1.15) + 80(1.05)(1.1)(1.05) + 20(1.2)(1.15)(1.1) + 0(1.1)(1.05)(1.1) + 20(1.15)(1.15)(1.1)

= 786 + 404 + 97 + 30 + 64 + 29 =  1410 MTOE

Hence the required percentage is $$\frac{786}{1410}\times100=\ 56\%\$$
