PSLE A group of pupils was asked to choose one taco from beef, vegetarian, egg and tuna. The table represents the pupils' choices. The pupils' choices were also represented by a bar graph but the names of the tacos were not shown. What was the total number of pupils who chose egg and beef tacos?
Tacos |
Pupils |
Beef |
40% |
Vegetarian |
10% |
Egg |
5% |
Tuna |
45% |
Number of pupils who chose egg tacos is the least. So it is represented by the shortest bar.
Number of pupils who chose egg tacos = 20
5% of pupils = 20
1% of pupils = 20 ÷ 5 = 4
Percent of pupils who chose beef tacos = 40%
Percent of pupils who chose vegetarian tacos = 10%
Percent of pupils who chose beef and vegetarian tacos
= 40% + 10%
= 50%
Total number of pupils who chose egg and beef tacos
= 50 x 4
= 200
Answer(s): 200
