### Solved Examples:

I. Directions (Qs. 1-5): Study the following table and answer the questions given below it.

Production of sugar by six major production units of India in Million Tonnes 1. In which month the unit B has a contribution of approximately 15% in the total sugar production?
1) August    2) June   3) July   4) April

2. Which of the following units shows continuous increase in production of sugar over months?
1) A   2) B   3) C   4) D

3. In the case of Unit E, in which of the following pairs of months the production of sugar was equal?
1) April & June   2) June & July   3) July & August   4) April & May

4. In the month of June, how many units have a share of more than 25% of the total production of sugar?
1) one   2) Three   3) Two   4) Four

5. What was approximate percentage decrease in sugar production of unit B in June as compared to April?
1) 8 %   2) 1 0%   3) 1 5%   4) 1 8%

6. Ans: 1 . (3) Total production in April
= 310+180+169+137+140+120=1056
15% of 1056 = 15/100x1056 = 158.4
Total Production in June
= 320 + 160 + 188 + 173 + 135 + 130 = 1106
15% 1106 = 15/100x1106 = 165.9
Total production in July
= 326+167+187+146+130=1136
15% of 1136 = 15/100x1136 = 170.4
Total Production in August
= 327+150+185+178+145+128= 1113
15% of 1113 = 15/100x1113 = 166.95 ~ 167
ie, in Month July, the Unit B has a contribution of approximately 15% in the total sugar production.

2 . (1) Unit A shows continuous increase in production of sugar over months.

3 . (4) In Unit E, the pair of months that shows equal sugar production is April and May.

4 . (1) Total Production in June =
320+160+188+173+135+130 = 1106
25% of 1106= 25/100x1106 = 276.5 units
ie, Unit A shows more than 25% of the total production of sugar in the month June.

5 . (2) In unit B, the production in June = 160 the production in April = 180 units Decrease in percentage
=(180-160/180)100 = 20/180x100
= 11.11% ~ 10%

II. Directions (Qs. 6-10): Study the following graph carefully and answer the questions given below it: 7. What was the price difference between commodity A and B in the month of April?
1) 250   2) 150   3) 100   4) 90

8. What was the difference in average price between commodity A and B from April to August?
1) 86   2) 75   3) 95   4) 85

9. In which of the following pairs of months was the price of commodity A same?
1) January - March   2) May-June   3) April- August   4) July-August

10. What was the approximate percentage decrease in the price of commodity A from March to April?
1) 1   2) 9   3) 14   4) 12

11. What was the percentage increase in price of commodity B from January to April?
1) 15   2) 20   3) 17   4) 10

12. Ans: 6 (2).The price of commodity A in April = 1000
The price of commodity B in April = 1150
Difference = 1150 - 1000 = 150

7) (b). Average price of commodity A from April to August
= 1000 1050 975 900 1000/5 = 4925/5 = 985
Average price of commodity B from April to August
= 1150 1100 1100 1000 950/5 = 5300/5 = 1060
Difference = 1060 - 985 = 75

8)(3) Price of commodity A in April = 1000
Price of commodity A in August = 1000
Therefore, in April - August the price of commodity A was same.

9)(4) Price of commodity A in March = 1125
Price of commodity A in April = 1000
Decrease
= (1125-1000/1125)100 = 125/1125x100
= 11.11% = 12%

10)(1)Price of commodity B in January= 1000
Price of commodity B in April = 1150
Increase
= (1150-1000/1000)100
= 150x100/1000 = 15%
