A) 256
B) 196
C) 284
D) 180
E) None of these
Correct Answer: A
Solution :
Let the total marks of examination be x. According to the question, \[\frac{50x}{100}-\frac{25x}{100}=56+144\] \[\Rightarrow \frac{25x}{100}=200\Rightarrow \frac{x}{4}=200\] \[\Rightarrow x=4\times 200=800\] \[\therefore \] Minimum passing marks \[=\frac{25x}{100}+56\] \[=\frac{800}{4}+56=200+56=256\]You need to login to perform this action.
