Given :

Number of students surveyed = 80

Students that like maths = 0.55

Students that like science = 15% or 0.15

So, Number of students that like maths = 80 × 0.55

= 44

Number of students that like science = 80 × 0.15

= 12

So, number of students that prefer maths over science = 44 - 12

= 32

Hence, option (B) is correct.
