Question 20
The incomplete bar graph below shows the number of ice-cream cones sold in 5 days. A total of 40 ice-cream cones were sold.
Draw the bar to show the number of ice-cream cones sold on Friday
Answer
10 cones
Explanation
Mon = 6 cones
Tue = 12 cones
Wed = 8 cones
Thur = 4 cones
Mon to Thur = 6+12+8+4 = 30 cones
Total cones = 40 cones
Therefore Friday cones = 40-30 = 10 cones
