Study The Diagram and Answer The Question Numbers A to D.
A. In how many months in 2012, the consumption of electric units was more than the average units consumption in that year?
- 3
- 4
- 5
- 2
B. The total units consumption in the year 2013 during these 5 months, in respect of the same in the previous year has been:
- decreased by 2.27%
- increased by 2.22%
- found unaltered
- increased by 2.27%
C. The maximum difference in the units consumption between these two years has been found in the months of:
- August
- October
- November
- July
D. The average electric consumption by the family during these 5 months in 2013 is:
- 400 units
- 440 units
- 450 units
- 470 units
A. Answer : (4) 2.
Explanation:-
The sum of unit consumption in 2012 = 600 + 700 + 400 + 300 + 200
= 2200
Then, the average of unit consumption in 2012 = 2200/5
= 440
2 months in 2012, the consumption of electric units was more than the average units consumption in that year.
Hence, the answer is (4) 2.
B. Answer:
Explanation: –
The total units consumption in the year 2012 = 600 + 700 + 400 + 300 + 200
= 2200
The total units consumption in the year 2013 = 550 + 500 + 400 + 350 + 450
= 2250
Increase consumption = 2250 – 2200
= 50
Increase in percent = 50 x 100/2200
= 2.27 %
Hence, the answer is (4) 2.27 %.
C. Answer: (3) November
Explanation:-
The maximum difference in the units consumption between these two years has been found in November = 450 – 200
= 250
Hence, the answer is (3) November.
D. Answer: (3) 450 units
Explanation:-
The sum of electric consumption by the family during these 5 months in 2013 = 550 + 500 + 400 + 350 + 450
= 2250
Then, the average of electric consumption by the family during these 5 months in 2013 = 2250/5
= 450
Hence, the answer is (3) 450 units.
