Let the number of students be X who cleared cut off in all sections.
The number of students who cleared the cutoff in section 1 and section 2, only = 20 – X
The number of students who cleared the cutoff in section 2 and section 3, only = 16 – X
The number of students who cleared the cutoff in section 1 and section 3, only = 26 – X
 
Now, consider section 1:
24 + 20 – x + x + 26 – x = 60
70 – x = 60
x = 10

And section 3, and 12 students cleared the cutoff in all three sections.

To find the total number of students who cleared the cutoff in at least one section, we add the number of students who cleared the cutoff in each section and subtract the number of students who cleared the cutoff in more than one section.

Total = (Students who cleared cutoff in section 1) + (Students who cleared cutoff in section 2) + (Students who cleared cutoff in section 3) - (Students who cleared cutoff in more than one section)

Total = 60 + 50 + 56 - (20 + 16 + 12)

Total = 166 - 48

Total = 118

Therefore, a total of 118 students cleared the cutoff in at least one section.
