1 student.

Step-by-step explanation:

No of students that like Reasoning = 129 - (85-54) - (89-54)

= 63

No of students that like Reasoning only = 63-54

= 9

No of students that like Calculus = 129 - (86-54) - (89-54)

= 62

No of students that like Calculus only = 62-54

= 8

No of students that like Algebra = 129 - (86-54) - (85-54)

= 66

No of students that like Algebra only = 66-54

= 12

No of students that like Algebra and Resoning only = (85-54)

= 31

No of students that like Algebra and Calculus only = (86-54)

= 32

No of students that like Reasoning and Calculus only = (89-54)

= 35

Total students = 182

Total students offering at least one module + total students offering none = Total students

182 = 9 + 8 + 12 + 31 + 32 + 35 + 54 + X

X = 182 - 181

= 1 student.
