Study the Diagram and Given Answer:
Study the following bar diagram carefully and answer the following Four Questions.
The number of the production of electronic items (TVS and LCDs) in a factory during the period from 2009 to 2013.
A. The total number of production of electronic items is maximum in the year
- 2010
- 2013
- 2011
- 2009
B. The difference between average of production of Tvs and LCDs from 2009 to 2012 is
- 800
- 900
- 600
- 700
C. The Ratio of production of Tvs in the years 2009 and 2010 is
- 3:2
- 2:3
- 6:7
- 7:6
D. The ratio of production of LCDs in the year 2011 and 2013 is
- 4:3
- 3:4
- 1:4
- 2:3
A. Answer: (3) 2011
Explanation:-
The maximum production of electronic item in 2011 = 13000 + 9000
= 22000
Then, the maximum production of electric item in 2011 is 23000.
Hence, the answer is (3) 2011.
B. Answer: (2) 900
Explanation:-
The total production of Tvs from 2009 to 2012 = 6000 + 9000 + 13000 + 11000
= 39000
Then, the average production of Tvs from 2009 to 2012 = 39000/4
= 9750
The total production of LCDs from 2009 to 2012 = 7000 + 9400 + 9000 + 10000
= 35400
Then, the average production of LCDs from 2009 to 2012 = 35400/4
= 8850
Then, the difference between average of production of Tvs and LCDs from 2009 to 2012 = 9750 – 8850 = 900
Hence, the answer is (2) 900.
C. Answer: (2) 2 : 3
Explanation: –
The total production of Tvs in 2009 = 6000
The total production of LCDs in 2012 = 9000
Then, the ratio of production of LCDs in the years 2009 and 2012 = 6000/900
= 6/9 = 2/3 = 2 : 3
Hence, the answer is (2) 2 : 3.
D.Answer : (2) 3 : 4
Explanation : –
The production of LCDs in the year 2011 = 9000
The production of LCDs in the year 2013 = 12000
Then, the ratio of LCDs in the year 2011 and 2013 = 9000 / 12000
= 9/12 = 3 : 4
Hence, the answer is (2) 3 : 4.
