PSLE
A group of pupils was asked to choose one rice set from mutton, turkey, egg and beef. The table represents the pupils' choices. The pupils' choices were also represented by a bar graph but the names of the rice sets were not shown. What was the total number of pupils who chose mutton and egg rice sets?

Rice Sets	Pupils
Mutton	5%
Turkey	25%
Egg	30%
Beef	40%

Number of pupils who chose mutton rice sets is the least. So it is represented by the shortest bar.

Number of pupils who chose mutton rice sets = 20

5% of pupils = 20

1% of pupils = 20 ÷ 5 = 4

Percent of pupils who chose mutton rice sets = 5%
Percent of pupils who chose egg rice sets = 30%

Percent of pupils who chose mutton and egg rice sets
= 5% + 30%
= 35%

Total number of pupils who chose mutton and egg rice sets
= 35 x 4
= 140

Answer(s): 140
