Students who choose all = x
Students who choose more than 1 subject = 1.4x
ie. Students who choose exactly 2 subjects = 1.4x - x = 0.4x
Total Students = 280 = 160+130+110 - 0.4x - 2*x
i.e. 2.4x = 120
i.e. x = 50
Answer: Option B
General Discussion
Bunuel
\(160+ 130+110 - 0.4x - 2x = 280\)
\(400- 2.4x = 280\)
\(2.4x = 120\)
--> \(x = \frac{120}{2.4}=\frac{1200}{24}= 50 \)
Answer (B).
