174 questions
Step-by-step explanation:
no.of even numbered questions = 25/2 -1
≈ 13-1 = 12.
no.of odd numbered questions = 25/2 ≈ 13.
total no.of even questions = 12×8 = 96.
total no.of odd questions = 13×8 = 104.
therefore total no.of questions correctly answered = 96 + 3/4 of 104
= 96 + (3/4)(104)
= 96 + (3×26)
= 96 + 78
= 174 questions.
