What is the average consumption of crude oil in each of the ten countries in 2010?
» Explain it
B
Total consumption of crude oil = (2300 + 1600 + 1900 + 2100 + 900 + 3100 + 5800 + 6000 + 5400 + 5200) + (300 + 400 + 500 + 400 + 1400 + 1300 + 300 + 450 + 550 + 400) – (600 + 500 + 500 + 800 + 300 + 2100 + 4400 + 5100 + 4200 + 4800) = 34300 + 6000 – 23300 = 17000 million gallons
 
Required average =  17000  = 1700 million gallons
10

Hence, option (B) is correct.

What is the average consumption of crude oil in each of the ten countries in 2012?
» Explain it
A
The table for year 2012 is as under

  Production Export Import Consumption
Afghanistan 2760 690 354 2760 + 354 – 690 = 2424
Bangladesh 2000 620 488 2000 + 488 – 620 = 1868
Bhutan 2375 625 600 2375 + 600 – 625 = 2350
India 2562 960 460 2562 + 460 – 960 = 2062
Maldives 1116 375 1708 1116 + 1708 – 375 = 2449
Nepal 3565 2352 1495 3565 + 1495 – 2352 = 2708
Pakistan 6844 5280 345 6844 + 345 – 5280 = 1909
Sri Lanka 6960 5763 526.5 6960 + 526.5 – 5763 = 1723.5
Dubai 6048 4704 605 6048 + 605 – 4704 = 1949
Abu Dhabi 5928 5280 460 5928 + 460 – 5280 = 1108

Required average
 
2424+1868+2350+2062+2449+2708+1909+1723.5+1949+1108
10

20550.5  = 2055.05 million gallons
10

Hence, option (A) is correct.

3
What is the export to import ratio of the 10 countries together in 2010?
» Explain it
C
The import of the 10 countries together = 300 + 400 + 500 + 400 + 1400 + 1300 + 300 + 450 + 550 + 400 = 6000 million gallons
 
The export of the 10 countries together = 600 + 500 + 500 + 800 + 300 + 2100 + 4400 + 5100 + 4200 + 4800 = 23300 million gallons
 
Required ratio = 233 : 60

Hence, option (C) is correct.
