In figure out which Number indicate doctors who are not married

1

The correct answer is Option 3: 1

Both 1 and 5 lie inside the triangle (Doctors) and outside the rectangle (Married People). Therefore, both represent doctors who are not married.

• 1 = Doctor only, not married
• 5 = Doctor + Professor, but not Married

Since the question asks for “doctors who are not married,” profession as professor does not matter. Hence, both regions should be included. However, because the options contain only single numbers, the answer key has considered only the exclusive “Doctor only” region, i.e., 1. Logically, though, 1 and 5 both satisfy the condition.
