Which of the following is the contrapositive of the statement: “If I do not obtain good marks, then I cannot pursue engineering”?

1. If I obtain good marks, then I can pursue engineering
2. If I pursue engineering, then I obtain good marks
3. If I cannot pursue engineering, then I do not obtain good marks
4. None of these

Correct answer: If I pursue engineering, then I obtain good marks

Solution

The statement is 'if not good marks (~G) then cannot pursue engineering (~E)', i.e. ~G => ~E. Its contrapositive is the negation of consequent implying negation of antecedent: E => G, that is 'If I pursue engineering, then I obtain good marks.'
