Average salary of an employee in a company is Rs. 30,000. All the employees are divides into three tiers each have different increments. If the average increment is 6% and the difference in increment in each tier is 1%.What is the average salary after increment if there is equal number of employees in each tier and total employees are 90? Correct Answer 31,800
Total salary of all the employees is Rs. 30,000 × 90 = 27,00,000
Total increment in first section = 30,000 × 30 × 0.05 = 45,000
Total increment in second section = 30,000 × 30 × 0.06 = 54,000
Total increment in third section = 30,000 × 30 × 0.07 = 63,000
Total increment = 1,62,000
Total salary after increment = 27,00,000 + 1,62,000 = 28,62,000
∴ Average salary = 28,62,000/90 = 31,800
