CAT MCQ scoring is +3 for correct, −1 for wrong. The expected value of a pure random guess on a 4-option MCQ is:

  1. $+3$ marks always
  2. $-1$ marks always
  3. Exactly $0$ marks
  4. $+1$ mark on average
Show answer and solution

Correct answer: C. Exactly $0$ marks

E = (1/4)(+3) + (3/4)(-1) = 0.75 − 0.75 = 0. Pure-random guesses on 4-option MCQs are zero-expectation. Worth attempting only if you can eliminate 1+ options.

A CAT QA word problem says 'the price was reduced from ₹100 to ₹85'. The percent change is:

  1. $+15\%$
  2. $-15\%$
  3. $-18\%$
  4. $+12\%$
Show answer and solution

Correct answer: B. $-15\%$

Percent change = (new − old)/old × 100 = (85 − 100)/100 × 100 = -15% (a decrease). **Sign-error trap:** positive 15% would mean a rise to ₹115.
