1) 189
2) 182
3) 243
4) 196

Read Solution (Total 1)

2) 182
If number of correct answer=x & Wrong answer=y
then x-0.25y=152 or 4x-y=608
Among the given options only the option 182 can give number of question as a whole integer
if x+y=182 y=182-x ,if substituted in above equation 4x-(182-x)=608 =>5x=790
x=158=Correct answers So Wrong answers=24
