ATQ, Let the total number of employees in the office be 100p. Number of employees who like Tea = 100p × (30/100) = 30p Number of employees who like Coffee = 100p × (42/100) = 42p Number of employees who like Juice = 100p – 30p – 42p = 28p 28p – (42p/2) = 280 28p – 21p = 280 7p = 280 p = 40 Total number of employees in the office = 100 × 40 = 4,000
