Directions ( 5- 8) : The bar graph provided below gives the sales of books (in thousand numbers) from six branches of a publishing company during two consecutive years 2000 and 2001. Answer the questions based on the graph.

5.    Total sales of the branches B1, B3 and B5 together for both the years (in thousand numbers) is :

(1) 550                               (2) 570

(3) 560                               (4) 580

6.    Total sales of branch B6 for both the years is what percent of the total sales of the branch B3 for both the years ?

(1) 70.17%                        (2) 71.17%

(3) 72.17%                        (4) 73.17%

7.    What is the average sale of all the branches (in thousand numbers) for the year 2000 ?

(1) 75                                 (2) 80

(3) 85                                 (4) 70

8.    What is the ratio of the total sales of branch B2 for both the years to the total sales of the branch B4 for both the years ?

(1) 4 : 9                              (2) 7 : 9

(3) 4 : 8                              (4) 7 : 10

ANSWERS WITH SOLUTIONS :

1.    (3) : Increase is = 145-108 = 37
Now we need to calculate that 37 is what percent of 108.
[(37/108)∗100]%=34.25%

2.    (4) : After analysing table chart, it is clear that the sales of 7AH batteries have been decreasing continuously from 1992 to 1997.

3.    (1) : The total sales (in thousands) of all the seven years for various batteries
are : a t.
For 4AH = 75 + 90 + 96 + 105 + 90 + 105 + 115 = 676
For 7AH = 144 + 126 + 114 + 90 + 75 + 60 + 85 = 694
For 32AH = 114 + 102 + 75 + 150 + 135 + 165 + 160 = 901
For 35 AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601
For 55 AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.
Clearly, sales are maximum in case of 32AH batteries.

4.    (2) : Required difference = [(84 - 45) * 1000] = 39000.

Directions : ( 5 – 8)

5.    (3) : Total sales of branches B1, B3 and B5 for both the years (in thousand numbers is)= (80+105)+(95+110)+(75+95)
= 560

6.    (4): Required Percentage =
[(70+80)/(95+110)∗100]%=150/205∗100%=73.17%

7.    (2) : Average sale of all the branches for the year 2000 is
1/6(80+75+95+85+75+70)
= 80

8.    (2) Required Ratio = (75+65)/(85+95)=140/180=7/9=7:9
