 Hello and welcome to this session. In this session we will discuss a question which says that Suppose 8 of its students are surveyed to know which ice cream flavor do they like, vanilla or chocolate The table shows the results of this survey. Now here you have to find out of 200 boys surveyed What percent prefer vanilla? Then the second part we have to find out of 600 girls surveyed What percent prefer chocolate? And in third part we have to find out of 610 preferred chocolate What percent are girls and boys? Now let us start with the solution of the given question Now on this table we are given two categories One is gender, that is boys and girls And other of ice cream flavors, that is chocolate and vanilla Now on the table we can read that out of 800 students, 600 are girls and 300 are boys Also you can see that 610 students like chocolate and 100 students like vanilla flavor And here 450 girls like chocolate and 150 girls like vanilla flavor Then 160 girls like chocolate flavor and 50 girls like vanilla flavor Now in the first part we have to find the percent of girls which prefer vanilla flavor For this we find proportion of boys prefer vanilla With given condition of 200 boys and then 99 by 100 So required percent is number of boys who like vanilla flavor That is 50 upon total number of boys That is 200 into 100 and this is equal to 20 percent So 20 percent out of 200 prefer vanilla flavor Now let us start with the second part And here we have to find percent of girls which prefer chocolate flavor So required percentage is number of girls who prefer chocolate flavor That is 450 upon total number of girls that is 600 into 100 And this is equal to 75 percent And in the third part we are given the condition that the student prefers chocolate Now we have to find what percent of students prefer chocolate are girls Now the total number of students prefer chocolate flavor is 110 And number of girls prefer chocolate flavor is equal to 450 So required percentage is equal to 450 upon 610 into 100 Which is equal to 73.8 percent So out of 610 students prefer chocolate flavor, 73.8 percent are girls Similarly we can find that what percent of students prefer chocolate are boys And this is equal to number of girls who prefer chocolate flavor That is 160 upon total number of students prefer chocolate flavor That is 610 into 100 And this is equal to 26.2 percent And this is the solution of the given question That is all for this session Hope you all have enjoyed the session
