Text Solution

Verified by Experts

The correct Answer is:
B
Candidates failed in Science = 191
So, candidates failed in science only
`= 191 - (62 +60 +48) = 21`.
Candidates failed in Social Science only = 15
Therefore, candidates passed in Maths and at-least one more subject
`= (21 + 15 + 167) = 203`
