Option 2 : 14%
According to the question, let the following Venn diagram,
Now,
e = 5%
b + e = 14%
⇒ b = 9%
and,
d + e = 18%
⇒ d = 13%
Therefore,
Percentage of students who failed only in Economics = a = 41% - (b + e + d)
a = 41% - (9 + 5 + 13)%
a = 41% - 27%
a = 14%
Hence, 14% is the correct answer.
