Question

A firm pays its five clerks Rs. 15,000 each, three assistants Rs. 40,000 each and its accountant Rs. 66,000. Then the mean salary in the firm comprising of these nine employees exceeds its median salary by rupees

Accepted Answer

A. Order of salaries for 9 employees: $15k, 15k, 15k, 15k, 15k, 40k, 40k, 40k, 66k$. Median (5th term) = Rs. 15,000. Total salary = $5(15,000) + 3(40,000) + 1(66,000) = 75,000 + 120,000 + 66,000 = 261,000$. Mean = $\frac{261,000}{9} = 29,000$. Difference = $29,000 - 15,000 = 14,000$.
