Answer 1

Answer:

B. M

Solution:

Arranging them according to the given information,

J teaches Arts on Saturday.

L teaches neither English nor Social Science, but he teaches on Thursday.

Wednesday is reserved for Maths taught by K.

Social Science is taught a day before Arts.

Day	Teacher	Subject
Monday
Tuesday
Wednesday	K	Maths
Thursday	L
Friday		Social Science
Saturday	J	Arts

 

L does not tech Social science and English, the two remaining subjects are Science and Hindi, but O teaches Science, so L teaches Hindi.

O teaches Science a day before N.

Only Social science is left, which is taught by M. 

Day	Teacher	Subject
Monday	O	Science
Tuesday	N	English
Wednesday	K	Maths
Thursday	L	Hindi
Friday	M	Social Science
Saturday	J	Arts

 

M teaches Social Science.

Hence, “M” is the correct answer.
