The number of employees in a company is 69. If there are 2 departments and the number of employees in first department is 30% more than the other department, find the ratio of employees in the second department to the employees in the first department.

Correct Answer: 10 : 13
Let the number of employees in the second department be x. The total number of employees = 69 The employees in the second department = x The employees in the first department = x + 30% of x = 1.3x The total number of employees = x + 1.3x = 2.3x 2.3x = 69 X = 30 The number of employees in the second department = 1.3x = 39 The required ratio = 30 : 39 = 10 : 13
