Tips for solving tables and graphs problems -
(1)= Read and view tables and diagram properly.
(2)= Put proper attention, what sum rows and sum of columns represents.
(3)= Take care regarding of units.
(4)= Try to understand the question, sometimes you can solve in your mind by just looking at data.
(5)= Most of the questions can be solved by approximation, thus you can save time by avoiding calculation.
Ex. Study the table and answers the questions.
Financial Statement of A company Over the years
(Rupees in Lakhs )
| Year | Gross Turnover | Profit before interesrt and depreciation | Interest Rs. | Deprciation Rs. | Net profit Rs. |
| 2000-01 | 1360.00 | 381.90 | 300.00 | 70.00 | 10.66 |
| 2001-02 | 1402.00 | 403.92 | 315.35 | 71.10 | 18.45 |
| 2002-03 | 1538.40 | 520.05 | 390.80 | 80.01 | 49.15 |
| 2003-04 | 2116.34 | 600.02 | 440.89 | 89.0 | 66.00 |
| 2005-06 | 2521.00 | 810.00 | 500.90 | 91.92 | 212.80 |
| 2006-07 | 2758.99 | 920.00 | 600.00 | 99.00 | 220.80 |
Q (1) During which year did the 'Net Profit ' exceed Rs. 1 crore for the first time ?
(a) 2006-07 (b)2005-06 (c) 2003-04
(d) 2002-03 (e) None of these
Solution :By looking at the table we find option (b) as correct
Q(2) During which year was the " Gross Turnover " closet to thrice the 'Profit before Interest and Depreciation' ?
(a) 2006-07 (b)2005-06 (c) 2003-04
(d) 2002-03 (e) 2001-02
Solution : Here we have to find out the ratio of "Gross turnover " to the "Profit before Interest and Depreciation "
for 2006-07 ratio = 2758.99 / 920 = 3.0 , since we get answer by hit and trial of first option only then we need not have to find other option.
So, correct option is (a) 2006-07
Q(3) During which of the given year did the 'Net profit ' form the highest proportion of the ' Profit before Interest and Depreciation ?
(a) 2005-06 (b) 2003-04 (c) 2002-03
(d) 2001-02 (e) 2000-01
Solution : Here we will find the reverse ths ratio between ( Profit before Interest and Depreciation / Net Profit ) and try to find lowest ratio also we use approximation for saving time
For 2005-06, 81 / 21 = 4 approx.
For 2003-04, 60 / 6.6 = 9 approx
For 2002-03, 520 / 50 = 10 approx
For 2001-02, 40 / 1.8 = 22 approx
For 2000-01, 380 / 10 = 38 approx
So, lowest ratio is for 2005-06 it means reverse ratio between (Net Profit / Profit before Interest and Depreciation ) will be highest, so option (a) is correct
Q(4) Which of the following registered the lowest increase in terms of rupees from the year 2005-06 to the year 2006-07 ?
(a) Gross turnover (b) Profit before interest and depreciation (c) Depreciation
(d) Interest (e) Net Profit
Solution : We calculation with approximation in mind
(a) 2758 - 2520= 2200 approx.
(b) 92 -81 =11= 110 approx
(c) 99 - 91.92 = 08.09 approx
(d) 600 - 505 = 95 approx
(e) 220 - 212= 08 approx
So correct option is (e) Net profit
Q(5) The gross Turnover for 2002-03 is of what percentage of the 'Gross Turnover ' for 2005-06 ?
(a) 61 (b) 163 (c) 0.611
(d) 39 (e) 0.006
Solution : 2002-03 Gross Turnover 1538.40
For 2005-06 Gross Turnover 2521.00
So option (a) is correct

| Girish | 92 | 82 | 81 | 79 | 49 | 30 | 61 |
| Vivek | 55 | 70 | 65 | 69 | 44 | 28 | 30 |
Q(1) How many students have scored the lowest marks in two or more subjects ?
(a) 2 (b) 3 (c) 1
(d) 0 (e)4
Solution :Here option (a) is correct by looking at table we find Chaman and Vivek has scored lowest marks in two or more subjects
Vivek in Hindi, Science, Phy. Edu
Chaman in Social std, Sanskrit
Q(2) Who has scored the highest marks in all the subjects together ?
(a) Devendar (b) Chaman (c) Anupam
(d) Girish (e)Bimal
Solution : For this calculate total toatal of each students in options
Devendar = 65 + 62 + 69 + 81 + 70 + 40 + 50 = 437
Chaman = 64 + 78 + 74 + 63 + 55 + 25 + 53 = 412
Anupam = 85 + 95 + 87 + 87 + 65 + 35 + 71 = 525
Girish = 92 + 82 + 81 + 79 + 49 + 30 + 61= 474
Bimal = 72 + 97 + 55 + 77 + 62 + 41 + 64 = 468
So correct option is (3) Anupam
Q (3) What is the percentage of Devendar's marks (upto two digits after decimal) in all the subjects together ?
(a) 88.63 (b) 77.38 (c) 67.83
(d) 62.83 (e)72.83
Solution : Devendar's total marks = 437
Q (4) Marks obtained by Chaman in Hindi are what percentage of marks ( upto two digits after decimal ) obtained by Anupam in the same subject ?
(a) 75.92 (b) 78.38 (c) 77.29

(a) 55.75 (b) 57.50 (c) 60.00
(d) 59.50 (e)58.00
Solution : Average maks obtained in Science =
So, option (b) true
