PSLE The bar graphs show the sale of child tickets and adult tickets to a funfair over four days. The scale of the graph for adult tickets is not shown.
- How many child tickets were sold in total on Monday and Wednesday?
- The ratio of the number of adult tickets sold on Wednesday to the total number of tickets sold on that day was 5 : 6. How many adult tickets were sold on Tuesday?
(a)
Number of child tickets sold on Monday = 20
Number of child tickets sold on Tuesday = 120
Number of child tickets sold on Wednesday = 60
Number of child tickets sold on Thursday = 100
Total number of child tickets sold on Monday and Wednesday
= 20 + 60
= 80
(b)
Total number of tickets sold on Wednesday = 6 u
Number of adult tickets sold on Wednesday = 5 u
Number of child tickets sold on Wednesday
= 6 u - 5 u
= 1 u
1 u = 60
Number of adult tickets sold on Wednesday
= 5 u
= 5 x 60
= 300
2 p = 300
1 p = 300 ÷ 2 = 150
Number of adult tickets sold on Tuesday
= 1 p
= 1 x 150
= 150
Answer(s): (a) 80; (b) 150
