    Solution

    ATQ,
    Science students in 2022 = 5000 × 0.60 = 3000

    Commerce students in 2022 = 5000 − 3000 = 2000

    Science in 2023 = 3000 × (4/3) = 4000

    Commerce in 2023 = 2000 × 0.8 = 1600

    Total students in 2023 = 4000 + 1600 = 5600

    Percentage change = ((5600 − 5000)/5000) × 100 = 12%
