36. TABULATION This section comprises of questions in which certain data regarding common disciplines as production over a period of a few years: imports, exports, incomes of employees in a factory, students applying for and qualifying a certain field of study etc. are given in the form of a table. The candidate is required to understand the given information and thereafter answer the given questions on the basis of comparative analysis of the data. Thus, here the data collected by the investigator are arranged in a systematic form in a table called the tabular form. In order to avoid some heads again and again, tables are made consisting of horizontal lines called rows and vertical lines called columns with distinctive heads, known as captions. Units of measurements are given with the captions. SOLVED EXAMPLES The following table gives the sales of batteries manufactured by a company lit the years. Study the table and answer the questions that follow: (S.B.I.P.O. 1998) NUMBER OF DIFFERENT TYPES OF BATTERIES SOLD BY A COMPANY OVER THE YEARS (NUMBERS _N THOUSANDS) TYPES OF BATTERIES Year 4AH 7AH 32AH 35AH 55AH T0TAL 1992 75 144 114 102 108 543 1993 90 126 102 84 426 528 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. The total sales of all the seven years is the maximum for which battery ? (a) 4AH (b) 7AH (c) 32AH (d) 35AH (e) 55AH 2. What is the difference in the number of 35AH batteries sold in 1993 and 1997 ? (a) 24000 (b) 28000 (c) 35000 (d) 39000 (e) 42000 3. 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 (e) 1998 4. In the case of which battery there was a continuous decrease in sales from 1992 to 1997 ? (8) 4AH (b) 7 AH (c) 32AH (d) 35AH (e) 55AH 5. 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% (e)37% Sol. 1. (c) : 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 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. 2.
