(a)
Fraction of the pupils that like guinea pigs and hamsters
=
12 +
110=

110=
610=
35Fraction of the pupils that liked spiders

35=
55 -
35=
25(b)
Difference between the fraction of the pupils that like guinea pigs and fraction of the pupils that like spiders
=
12 -
25=
510 -
410=
110Total number of pupils = 10 u
Number of pupils that like guinea pigs more than spiders = 1 u
1 u = 11
Total number of pupils
= 10 u
= 10 x 11
= 110
Answer(s): (a)
