SOLUTION

1).

Total domestic investment in 2011 = 5000 + 3000 + 4000 + 2000 + 2500 + 1500 + 3500 = Rs.21500 Crore
Total foreign investment in 2011 = 2000 + 1600 + 2800 + 3000 + 2000 + 2500 + 1000
= Rs.14900 Crore
So, required difference = 21500 - 14900 = Rs.6600 Crore

2). 
Total investment in Metals = 4000 + 2800 + 3500 + 2000 + 3200 + 2200 + 1500 + 500
= Rs.19700 Crore
Total investment in Machinery = 2000 + 3000 + 2500 + 3000 + 3600 + 6000 + 1000 + 1500 = Rs.22600 Crore
So, required ratio = 19700 : 22600 = 197 : 226

3). 
Average domestic investment in 2014
= (6000 + 4000 + 1500 + 1000 + 4000 + 1200 + 2000) / 7
= 19700 / 7 = Rs.2814.28 Crore

4). 
Domestic investment in 2013 = 4000 + 5000 + 3200 + 3600 + 3000 + 1500 + 2400
= Rs.22700 Crore
Foreign investment in 2011 = 2000 + 1600 + 2800 + 3000 + 2000 + 2500 + 1000
= Rs.14900 Crore
= (22700 × 100) / 14900 = 152.3%

5).
Average domestic investment in 2011 = Rs. 21500 / 7 Crore
Average investment in transport
=(2500+ 2000 + 1500 + 3200 + 3000 + 1600 + 4000 + 1000) / 4 = Rs.4700 Crore
So, required % = [ 21500 / (7 × 4700) ] × 100 = 65.34%
