Five subjects, R, T, V, X and Z, are taught from Monday to Friday (not necessarily in the same order). One subject is taught on one day. Only Z is taught before R. T is taught before X. T is not taught on Wednesday. How many subjects are taught before V? Correct Answer 2

1. Only Z is taught before R. (Means R taught on Tuesday because only Z is taught before R)

2. T is not taught on Wednesday.

3. T is taught before X. (So, T is taught on Thursday because T is not taught on Wednesday)

4. V is taught on remaining day that is Wednesday.

So, there are 2 subject taught before V.
