are staff. 50% of managers and 75% of staff were promoted. Find the ratio of the number of managers who were promoted to the number of staff who were not promoted.Solution
ATQ,
Let the total number of employees be 100n. Number of managers = 0.4 × 100n = 40n. Number of staff = 100n - 40n = 60n. Number of managers promoted = 0.5 × 40n = 20n. Number of staff not promoted = 0.25 × 60n = 15n. Required ratio = 20n:15n = 4:3.
