# 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.
