In one of the questions that I solved, the stem reads as "In right angled triangle ABC ...."
My question is can we safely deduce from the stem that the triangle is right angled at B?
In my school we were taught that in a right angle triangle it is always the middle angle (as per the naming) that is a right triangle. is this information correct?

Do not assume it to be the case.
A triangle can be named as ABC, BCA,CAB but in all the cases the right angle, if any, might be at angle B.
Hence do not assume the position of the angle unless mentioned explicitly.

Hi klrahul ,
No, this is not allowed. If you are given a figure that displays angle B as right, then it's fine. If not, you cannot assume angle B is right angled. You must have the information "right angled at B".
Unfortunately, what you read in school is wrong.
Good luck
