The following table gives the sales of batteries manufactured by a company over the years.

Number of Different Types of Batteries Sold by a Company Over the Years (Numbers in Thousands)

Year Types of Batteries

4AH 7AH 32AH 35AH 55AH Total

1992 75 144 114 102 108 543

1993 90 126 102 84 126 528

1994 96 114 75 105 135 525

1995 105 90 150 90 75 510

1996 90 75 135 75 90 465

1997 105 60 165 45 120 495

1998 115 85 160 100 145 605

1.

What was the approximate percentage increase in the sales of 55AH batteries in 1998 compared to that in 1992?

A.	28%
B.	31%
C.	33%
D.	34%

Answer: Option D

Explanation:

Required percentage

= (145 - 108) x 100 %

108

= 34.26%

34%.

2.

The total sales of all the seven years is the maximum for which battery?

A.	4AH
B.	7AH
C.	32AH
D.	35AH

Answer: Option C

Explanation:

The total sales (in thousands) of all the seven years for various batteries are:

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 35AH = 102 + 84 + 105 + 90 + 75 + 45 + 100 = 601

For 55AH = 108 + 126 + 135 + 75 + 90 + 120 + 145 = 799.

Clearly, sales are maximum in case of 32AH batteries.

3.

What is the difference in the number of 35AH batteries sold in 1993 and 1997?

A.	24000
B.	28000
C.	35000
D.	39000

Answer: Option D

Explanation:

Required difference = [(84 - 45) x 1000] = 39000.

4.

The percentage of 4AH batteries sold to the total number of batteries sold was maximum in the year?

A.	1994
B.	1995
C.	1996
D.	1997

Answer: Option D

Explanation:

The percentages of sales of 4AH batteries to the total sales in different years are:

For 1992 = 75 x 100 % = 13.81%.

543

For 1993 = 90 x 100 % = 17.05%.

528

For 1994 = 96 x 100 % = 18.29%.

525

For 1995 = 105 x 100 % = 20.59%.

510

For 1996 = 96 x 100 % = 19.35%.

465

For 1997 = 105 x 100 % = 21.21%.

495

For 1998 = 115 x 100 % = 19.01%.

605

Clearly, the percentage is maximum in 1997.

5.

In case of which battery there was a continuous decrease in sales from 1992 to 1997?

A.	4AH
B.	7AH
C.	32AH
D.	35AH

Answer: Option B

Explanation:

From the table it is clear that the sales of 7AH batteries have been decreasing continuously from 1992 to 1997.
