A student needs 40% marks to pass. He gets 178 marks and fails by 22 marks. What are the maximum marks?
A. 550
B. 500
C. 445
D. 450
A. 550
B. 500
C. 445
D. 450
Best answer
Answer: B. 500
Answer: (B) 500
Shortcut: pass mark = 178 + 22 = 200 = 40% of maximum. Maximum = 200 × \(\frac{100}{40}\) = 500.
Trap: 178/0.4 = 445 ignores the 22 marks he fell short by.
