PSLE The bar graphs show the sale of child tickets and adult tickets to a tourist attraction over four days. The scale of the graph for adult tickets is not shown.
- How many child tickets were sold in total on Tuesday and Thursday?
- The ratio of the number of adult tickets sold on Monday to the total number of tickets sold on that day was 5 : 6. How many adult tickets were sold on Thursday?
(a)
Number of child tickets sold on Monday = 30
Number of child tickets sold on Tuesday = 50
Number of child tickets sold on Wednesday = 40
Number of child tickets sold on Thursday = 10
Total number of child tickets sold on Tuesday and Thursday
= 50 + 10
= 60
(b)
Total number of tickets sold on Monday = 6 u
Number of adult tickets sold on Monday = 5 u
Number of child tickets sold on Monday
= 6 u - 5 u
= 1 u
1 u = 30
Number of adult tickets sold on Monday
= 5 u
= 5 x 30
= 150
1 p = 150
1 p = 150 ÷ 1 = 150
Number of adult tickets sold on Thursday
= 3 p
= 3 x 150
= 450
Answer(s): (a) 60; (b) 450
