Syllogism questions are often asked in various competitive exams like CAT, XAT, UPSC, SBI PO and many other exams. The key to crack the logical reasoning section with questions from syllogism is to carefully understand the statement and conclusions.
Upon understanding the question asked, candidates should make sure that they do not get confused with the bunch of conclusions and pick the right fitting answer against the questions.
Here we discuss the various models of syllogism questions.
Statement: All the scientists are girls. All the girls are dancers.
Conclusions:
All the scientists are dancers.
Some girls are scientists.

Hence, we can conclude that the third conclusion is the only one which is true.
