 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that the table shows the percentage of Mr. Lawson's income spent in each category per month draw a circle graph to represent the data. If Mr. Lawson's monthly salary is $2,285 then how much amount is spent on food? We know that a circle graph is a graph in the form of a circle that is divided into sectors. With each sector representing a part of a set of data and to draw a circle graph we need to find the appropriate angle measure for each sector such that the sum of angles of all these sectors is 360 degrees. With this key idea we shall proceed to the solution. We are given a table which shows the per month expenditure of Mr. Lawson in percentage. It is given that Mr. Lawson spends 25% of his income on rent, 20% of his income on savings, 30% of his income is spent on food, 10% of his income is spent on clothing and 15% of his income is spent on other items. Now we have to draw its circle graph. From the key idea we know that to draw a circle graph we need to find the appropriate angle measure for each sector such that the sum of angles of all these sectors is 360 degrees. Here since we are given percentages so we directly find the angle measure for each category by multiplying each percentage with 360 degrees so first we find angle measure for category rent. Now 25% is spent on rent so its degree measure will be equal to 25% of 360 degrees and this is equal to 25 upon 100 into 360 degrees. On solving it further we get 2 into 5 is 10 and 2 into 18 is 36, 5 into 5 is 25 so now we are left with 5 into 18 degrees which is equal to 90 degrees. So angle measure for rent is 90 degrees similarly angle measure for savings will be equal to 20% of 360 degrees and this is equal to 20 upon 100 into 360 degrees and this is equal to 2 into 5 is 10 and 5 into 72 is 360 so this is equal to 72 degrees. So angle measure for savings is 72 degrees similarly angle measure for food will be equal to 30% of 360 degrees that is equal to 30 upon 100 into 360 degrees and this is equal to 3 into 36 degrees that is 108 degrees so angle measure for food is 108 degrees. Similarly angle measure for clothing is equal to 36 degrees and angle measure for other items is equal to 54 degrees. So now we have got the angle measure for rent is 90 degrees for savings its 72 degrees for food its 108 degrees for clothing its 36 degrees and for other items its 54 degrees. Here we should note that sum of all angle measures that is 90 degrees plus 72 degrees plus 108 degrees plus 36 degrees plus 54 degrees is equal to 360 degrees. Now we shall draw the circle graph first we draw a circle now angle measure for category rent is 90 degrees so using protractor we measure 90 degrees and draw the sector. Now we label it rent with percentage 25 now using protractor we draw the sectors for all the other categories with the given angle measure and label them accordingly. So this is the required circle graph showing Mr. Lawson's monthly expenditure now if Mr. Lawson's monthly salary is $2,285 then we have to find how much amount is spent on food and we are given that 30% of his income is spent on food so amount spent on food will be equal to 30% of his income that is $2,285 and this is equal to 30 upon 100 into $2,285 now on solving it further we get $685.5 So we say that $685.5 are spent on food per month and this is the required answer this completes our session hope you enjoyed this session.
