PSLE The bar graph shows the number of visitors to a stadium 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 108 more than the average number of visitors from Monday to Friday. If the number of visitors on Sunday was 700, how many visitors were there on Saturday?
(a)
Total number of visitors from Monday to Friday last week
= 620 + 580 + 280 + 560 + 620
= 2660
Average number of visitors from Monday to Friday last week
= 2660 ÷ 5
= 532
(b)
Average number of visitors on Saturday and Sunday
= 532 + 108
= 640
Total number of visitors on Saturday and Sunday
= 2 x 640
= 1280
Number of visitors on Saturday
= 1280 - 700
= 580
Answer(s): (a) 532; (b) 580
