**Answer the following question based on the information given below.**

There are 100 employees in an organization across five departments. The following table gives the department-wise distribution of average age, average basic pay and allowances. The gross pay of an employee is the sum of his/her basic pay and allowances.

Department | Number of Employees | Average Age (years) | Average Basic Pay (Rs) | Allowances (% of Basic Pay) |

HR | 5 | 45 | 5000 | 70 |

Marketing | 30 | 35 | 6000 | 80 |

Finance | 20 | 30 | 6500 | 60 |

Business Development | 35 | 42 | 7500 | 75 |

Maintenance | 10 | 35 | 5500 | 50 |

There are limited number of employees considered for transfer/promotion across departments. Whenever a person is transferred/promoted from a department of lower average age to a department of higher average age, he/she will get an additional allowance of 10% of basic pay over and above his/her current allowance. There will not be any change in pay structure if a person is transferred/promoted from a department with higher average age to a department with lower average age.

There was a mutual transfer of an employee between Marketing and Finance departments and transfer of one employee from Marketing to HR. As a result the average age of Finance department increased by one year and that of Marketing department remained the same. What is the new average age of HR department?

- 30
- 35
- 40
- 45
- cannot be determined

Best answer

Since the average age of finance department increased by 1, the total age became 31*20=620.

Initially total age= 30*20=600.

Therefore there is a net increase of age by 20 years. Hence the decrease in total age of Marketting department will be also 20. But since average age of marketing department is not changed , therefore-

total age after transfer from marketting to HR dept= 29*35=1015.

Initial total= 30*35=1050.

Decrease in total due to transfer from marketing to Finance dept=20. But total has to be maintained at 1015.

Therefore HR dept age total must have been increased by 35-20=15.

Hence new average of HR= 45*5+15=240.
