Correct Answer: 606154

Solution : From the table,
The total bonus for managers = 3 × 60 × 0.30 = Rs. 54 lakh
The total bonus for executives = 6 × 12 × 0.30 = Rs. 21.6 lakh
The total bonus for trainees = 4 × 4 × 0.20 = Rs. 3.2 lakh
The total bonus for all employees = 54 + 21.6 + 3.2 = Rs. 78.8 lakh
The total bonus for all employees (in Rs.) = Rs. 7880000
The total number of employees = 3 + 6 + 4 = 13
The average bonus per employee = $\frac{7880000}{13}$ = Rs. 606154
Hence, the correct answer is 606154.
