    and the rest were managers. In 2023, if the number of engineers increased by 20% and the number of managers decreased by 10%, find the percentage change in total employees.
    A 12% Correct Answer Incorrect Answer
    B 15% Correct Answer Incorrect Answer
    C 17% Correct Answer Incorrect Answer
    D 11% Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,
    Number of engineers in 2022 = 6000 × 0.70 = 4200

    Number of managers in 2022 = 6000 − 4200 = 1800

    Number of engineers in 2023 = 4200 × 1.20 = 5040

    Number of managers in 2023 = 1800 × 0.90 = 1620

    Total employees in 2023 = 5040 + 1620 = 6660

    Percentage change = ((6660 − 6000)/6000) × 100 = 11%
