Question
Study the given graph and answer the question that
follows. Break up for distribution (degree wise) of the employees working in five departments (A, B, C, D and E) in a company.  The total number of employees working in departments A and C exceeds the total number of employees working in departments B and D by x. The value of x lies between:Solution
Total number of employees in department A and B = 79.2° + 57.6° = 136.8° Total number of employees in department C = 122.4° Number of employees in A and B is more than that of C by = 136.8° – 122.4° = 14.4° Number of employees in A and B is more than C by = 3200 × 14.4/360 = 128 As we know, 128 lies between 120 and 140.
