# 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?

1.  3
2.  4
3.  5
4.  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:

1.  decreased by 2.27%
2.  increased by 2.22%
3. found unaltered
4. increased by 2.27%

C. The maximum difference in the units consumption between these two years has been found in the months of:

1.  August
2. October
3. November
4. July

D. The average electric consumption by the family during these 5 months in 2013 is:

1.  400 units
2. 440 units
3. 450 units
4. 470 units

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.

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 %.

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.
