Explanation:
The mean salary of the five vice presidents is Rs. 8 lakhs. So, the sum of their salaries = 5 × 8 = 40 lakhs. Let their salaries in ascending order be a, b, c, d and e. a + b + c + d + e = 40 The median salary is Rs. 8 lakhs So, c's salary is Rs. 8 lakhs. The only mode is Rs. 11 lakhs. So, Rs. 11 lakhs salary is drawn by the maximum number of VPs. C's salary is Rs. 8 lakhs So, d and e have to draw Rs. 11 lakhs each a + b + 8 + 11 + 11 = 40 a + b = 10 Their salaries are in integer lakhs. Therefore, a can draw Rs. 3 lakh and b can draw Rs. 7 lakh or a can draw Rs. 4 lakh and b can draw Rs. 6 lakhs or a and b can both draw Rs. 5 lakhs each. However, there is only one mode. So, a and b cannot draw Rs. 5 lakhs each and lowest salary cannot be odd number. So, a draws Rs. 4 lakhs (the least salary) and e draws Rs.11 lakhs (the highest salary). So, a + e = Rs. 15 lakhs
