PSLE The bar graph shows the number of visitors to a safari park from Monday to Friday last week.
- What was the average number of visitors from Monday to Friday last week?
- The average number of visitors on Sunday and Saturday was 188 more than the average number of visitors from Monday to Friday. If the number of visitors on Sunday was 300, how many visitors were there on Saturday?
(a)
Total number of visitors from Monday to Friday last week
= 360 + 390 + 110 + 120 + 360
= 1340
Average number of visitors from Monday to Friday last week
= 1340 ÷ 5
= 268
(b)
Average number of visitors on Saturday and Sunday
= 268 + 188
= 456
Total number of visitors on Saturday and Sunday
= 2 x 456
= 912
Number of visitors on Saturday
= 912 - 300
= 612
Answer(s): (a) 268; (b) 612
