The previous module we learned about sub divided bar diagram in this model also will be seeing one more sum based on sub divided bar diagram so let’s take up the question the question is this exercise 7.2 question number three the figures of income and expenditure in crores of rupees of a company are given draw a sub divided bar diagram for the following information right and what information is given it is given in the form of a table like this in the first row is it an year 2004-5 2005-6 2006-7 and 2007-8 right four years are there and then for each year what was the income of the company what was the expenditure of the company that is also given ok now what we have to do in this sum is we need to draw a sub divided bar diagram for a sub divided bar diagram what do we need we have income and we have expenditure for the year 2004-5 but for sum divided diagram what we require we require the total amount for each year for each year we require the total amount so what we will prepare one more table we’re in will have the total amount also that one more table also will have seen three columns the first row will be year the second income and third expenditure one more row will come that one more row will be for total alright so what we will do in this total for the year 2004-5 what is the total amount will add these two figures 155 + 140 will add and write it as 303 for the year 2005-6will add these two figures 162 and 152 will add it and it is 314 for the year 2006-7 will add these to 181 + 169 it will be 350 for the year 2007-8 add these two also 190 + 72 the total is 362 the table is ready right the total amount we got the table is ready now we can take up our graph paper after taking up our graph paper will draw the x-axis and y-axis leaving two centimeters from the bottom will draw the horizontal x-axis living two centimeters from the left will draw the vertical Y axis and then write X0, X’ and why Y0, Y’ now in this sum to information’s are given one is a subjective information which is the year 2004-5 2005-6, 6-7-8, 7 it right there is a subjective information and the numerical information is the amount the income and expenditure the total is what the amount that is a numerical information so what we will do on the x axis will mark the subjective information with his years and on the y-axis we are going to mark the numerical information and the numerical information is nothing but that amount in rupees right so x-axis and y-axis we are marked now for each year we will have to draw one bar and then divided which bar we are going to draw we are going to draw a rectangular bar which is of the length equal to the total right so what is a maximum amount in the total column you’ll see the maximum amount of the total column if you see the maximum amount in the total column it is 362 can you see that so you are a graph should accommodate this number 362 now how you will accommodate this number 362 do let us think about the scale we cannot take one centimeter is equal to 1 unit so we have increase scale now since we have about 20 centimeters with us what we will do on the y-axis we will consider the scale 1 centimeter is equal to 20 units ok because if one centimeter is 20 units we have got 20 centimeters with us 20 into 20 we can accommodate four hundred and we just have to accommodate this 362 right so what we will take the scale 1 centimeter is equal to 20 units but what is a unit in this sum it is crores of rupees right four units is crores of rupees so what would write the scale on the y-axis one centimeter is equal to rupees 20 crores and if it that is a scale on the y-axis to how Y axis is going to progress 20 40 60 80 100 120 140 160 180 200 220 240 260 280 300 320 340 360 380 so we can write up the 380 because we have to just accommodate this 362 right now for on the x-axis we are going to write the years now for each year for the year 2004-5 what we’ll have to do draw a rectangle of length 303 now how will you draw a rectangle of length 3 03 on this graph paper let us understand for that let us understand the scale properly right so let us understand the scale, scale we have taken one centimeter is equal to 20 crore so what is one centimeter your graph paper is made up of squares like this and the size of every square is 1 centimeter right and we have taken the scale 1 centimeter is equal to rupees 20 crores we are taken but one centimeter if you can’t no one two three four if you count small, small boxes are there 1 centimeter has got ten boxes and one centimeter is equal to 20 crores means 10 boxes is equals to 20 crores right if ten boxes is 20 crores then one box is nothing but the rupees 2 crores right so every one small box is equal so much 2 crore so just remember that now we want to mark 303 so let us understand where will this 303 lie 303 will lie between 300 and 320 yes or no 300 and 320 lie where will the 303 lie let us understand that because we understood that everyone box is equal 2 Crores right there is 303 like 300 is there down if you go up one box we reach 302 if you got one more box will reach 304 so between like 302 and 304 that line will represent 303 approximately on your graph paper all right so let us draw one rectangular bar up to 303 ok it is exactly between 300 and 320 and 300 just go up one box you reach 302 one more you reach 304 so between the second and the third box after 300 will be our 303 so let us draw that rectangular bar for the year 2004-5 right similarly let us draw for the year 2005-6 it is 314 right so 314 it is draw a rectangle of length 314 the scale understood the scale is one box is equals to 2 crore .314 how will you mark 314 will also lie between 300 and 320 so if you go up one box you’ll reach 302 one more 304 one more 306 one more 308 one more 310 one more you go up you reach 312 one more you go up it is 314 that means after the fifth box the light line is they’re of your graph paper just two boxes about that is 314 between 300 and 320 so it is marked for that also so that second rectangle up to the length of 314 Right the third one is 350,350 for the year 2006-7 350 will Iie exactly between 340 and 360 so we’ll draw a rectangle of length 350 right for the year two thousand six seven it will lie exactly between 340 and 360 so one box is 2 crores right so 340 is there a 360 is there exactly between 340 360 so just go up one box which 342 one more 344 one more 346 one more 348 and the next one is 350 so we are going to draw a rectangle up to 350 so that is the rectangle up to 350 for the year two thousand six seven and then last the last is 362 so for the 2007-8 draw a rectangle of length 362 so 362 how are you going to mark one box is 2 crores right so one box 360 is there here and 380, 362 is going to lie exactly between in 360 and 380 just one box which 362 right so that’s how we mark 362 so all the total bars we are drawn for all the years now we have to divide it it’s a sub divided bar diagram we are provided right let us subdivide these rectangles as income and expenditure so let us take the first year that is 2004-5 the income is 155 so let us mark 155 in the first year ok so one will provide the same way how you do the total bus same way to draw 155, 155 I will lie between 140 and 166 the next income is 162, 162 to lie between 160 and 180 the next income is 181, 181 will lie between 180 and 200 the next income is 190, 190 will also lie between 180 and 200 so we are marked all the incomes so the shaded region represents income and the unshaded region automatically presents expenditure because we are drawn that total bar so let us show indicators the shaded region represents income and the unshaded region represents expenditure right so let us write that expenditure so that completes you are subdivided bar diagram thank you.
