Answer» Correct Answer - Option 4 : \(71 \frac{3}{7}\)% Given: Initial salary = Rs. 7000 Increased salary = Rs. 12,000 Calculation: Increase in salary = Rs. 12000 – Rs. 7000 = Rs. 5000 Increase % in salary = (5000/7000) × 100 \(\Rightarrow 71\frac{3}{7}\)% ∴ The percentage increase in the salary is \(71\frac{3}{7}\)% |
