Chinara and Adaku compare their scores from five mental maths tests. The compound bar chart shows their test scores. In each test there was a total possible score of 10 . Write Adaku's total score for the five tests as a percentage.

Here we have, There are total number test is 5 and marks of each test is 10 . So, total marks is 5 × 10 = 50 . The blue bar goes to till 7 . So, Adaku got 7 in first test. The orange bar goes to till 13 . So, He got 13 - 7 = 6 in his second test. The grey bar goes to till 22 . So, he got 22 - 13 = 9 in his third test. The yellow bar goes to till 29 . So, he got 29 - 22 = 7 in his fourth test. The blue bar goes to till 35 . So, he got 35 - 29 = 6 in his fifth test. Thus, Adaku's total score in five test = 7 + 6 + 9 + 7 + 6 = 35 So, the Adaku's total score for the five tests as a percentage = 35 50 × 100 = 70 % Hence, the Adaku's total score for the five tests as a percentage is 70 %

This two-way table shows the number of holidays sold by a travel agency in a period of two weeks. Type of holidays beach sport city safari Week 1 10 5 4 1 Week 2 5 1 8 2 Copy the compound bar chart shown and use the information in the two-way table to complete the chart.

Given, Type of holidays beach sport city safari Week 1 10 5 4 1 Week 2 5 1 8 2 Also, we have Here, blue bar represents number of holidays sold in beach. Orange bar represents number of holidays sold in sport. Grey represents the number of holidays sold in city and yellow represents the number of holidays sold in safari. Consider week 1 , The length of the bar which represents the number of holidays sold in city = 15 + 4 = 19 The length of the bar which represents the number of holidays sold in safari = 19 + 1 = 20 Consider week 2 , The length of the bar which represents the number of holidays sold in sport = 5 + 1 = 6 The length of the bar which represents the number of holidays sold in city = 6 + 8 = 14 The length of the bar which represents the number of holidays sold in safari = 14 + 2 = 16

The compound bar chart shows the number of football matches won, lost and drawn by three teams. Copy this two-way table and use the information in the chart to complete the table. Won Lost Drawn Total Barcelona Real Madrid Valencia Total

Given, Here, the number of matches won by each team represents by blue bar, number of matches lost by each team represents by brown bar and number of matches drawn by each team represents by green bar. So, the number of matches Barcelona won is 19 . The number of matches Barcelona lost = 31 - 19 = 12 The number of matches Barcelona drawn = 35 - 31 = 4 So, total number of matches Barcelona played = 19 + 12 + 4 = 35 Now, the number of matches Real Madrid won is 16 . The number of matches Real Madrid lost = 25 - 16 = 9 The number of matches Real Madrid drawn 35 - 25 = 10 So, total number of matches Real Madrid played = 16 + 9 + 10 = 35 And, the number of matches Valencia won is 18 The number of matches Valencia lost = 23 - 18 = 5 The number of matches Valencia drawn = 35 - 23 = 12 So, the number of matches Valencia played = 18 + 5 + 12 = 35 Therefore, the complete table is, Won Lost Drawn Total Barcelona 19 12 4 35 Real Madrid 16 9 10 35 Valencia 18 5 12 35 Total 53 26 26 105

Chinara and Adaku compare their scores from five mental maths tests. The compound bar chart shows their test scores. In each test there was a total possible score of 10 . Write Adaku's total score for the five tests as a fraction.

Here we have, There are total number test is 5 and marks of each test is 10 . So, total marks is 5 × 10 = 50 . The blue bar goes to till 7 . So, Adaku got 7 in first test. The orange bar goes to till 13 . So, He got 13 - 7 = 6 in his second test. The grey bar goes to till 22 . So, he got 22 - 13 = 9 in his third test. The yellow bar goes to till 29 . So, he got 29 - 22 = 7 in his fourth test. The blue bar goes to till 35 . So, he got 35 - 29 = 6 in his fifth test. Thus, Adaku's total score in five test = 7 + 6 + 9 + 7 + 6 = 35 So, the Adaku's total score for the five tests as a fraction = 35 50 If we convert 35 50 in simplest form we get 35 ÷ 5 50 ÷ 5 = 7 10 Hence, the Adaku's total score for the five tests as a fraction is 7 10

This two-way table shows the number of cakes sold by a cafe on Saturday and Sunday. Chocolate Vanilla Saturday 18 7 Sunday 9 14 Draw a compound bar chart to show this information.

Given: Chocolate Vanilla Saturday 18 7 Sunday 9 14 A compound bar chart is a graph which combines two or more types of information in one chart. A compound bar chart is a type of bar chart where columns can be split into sections to show breakdown of data. On the y -axis, mark the days Saturday and Sunday. On the x -axis mark the number of cakes sold. Take one unit as one cake sold. Make one bar for Saturday and then spit it into parts. From 0 to 18 as one part with red colour and from 18 to 25 as one part with blue colour. Make one bar for Sunday and then spit it into parts. From 0 to 9 as one part with red colour and from 9 to 23 as one part with blue colour. Therefore, the compound bar graph is drawn below:

Given: Chocolate Vanilla Saturday 18 7 Sunday 9 14 In the above table, two sets of data are given. The best way to display this information is on a dual bar graph because a dual bar graph is a bar graph that displays two sets of data. And if we represent the information on a dual bar graph, it will be easier to interpret. The dual bar graph is shown below:
