Answer the following question based on the information given below.

The census officer provided the data regarding changes in population of three major towns - A, B and C for three years. Population of town A was 180600 in third year and it increased by 5% and 7.5% in second and third year respectively. Population of town B increased by 25% in second year which was same as 150% of population of town A in first year. After taking population control measures, town B succeeded in controlling population as growth rate in third year was half of that of previous year. The area of town C is 1250 km² and population density for second year was 250. Growth rate for town C was 11.11% and 10% for second and third year respectively.

Note : Population density = Total population / Total area. Growth rate is change in population over previous year for all towns and for all years.

1. Population of town B in third year exceeds how much by that of town A in second year?

Group Question

Answer the following question based on the information given below

The graph given above pertains to the recruitment and promotion details of a company called TFC. Every year, the company takes in new recruits, known popularly as “Nanos”, in the company for its off-shore projects. These Nanos remain Nanos for two years during which they undergo a rigorous training. Immediately after completion of two years of training, these Nanos appear for a screening test, following which they get promoted as Vets if they pass the test. For the number of Nanos that are recruited in a particular year, the number of Nanos getting converted into Vets is between 60% to 80% (only integral values of percentage), both values included. On conversion to Vets, these employees leave TFC operations in the country for on-shore projects. The Nanos who fail to get promoted as Vets continue as Nanos for one more year following which they are labeled as Vets without any test and are then transferred to its on-shore operations.

In the above chart, the innermost circle represents the year of intake of the Nanos, while the outer circles represent the numbers of Nanos and Vets for that year. Further for any given year, the number of Nanos always exceeds the number of Vets in the same year.

For example, in the year 2005, the number of Nanos that TFC had was 65 and the number of Vets in the same year was 42.

No employee can bypass the process and get recruited as a Vet directly.

The number of Nanos from the 2006 batch who were promoted as Vets without a test 3 was....

Badrinath College of Engineering (BCE) was established on 1^st May 1993 on the 60^th birth anniversary of Mr. Prakash Badrinath with 4, 5, 3 and 2 professors in Civil, Mechanical, Electrical and Information Technology department respectively. On 1^st of June 1993 one more professor joined. On every 1^st June of the subsequent years up to 1996 one professor is recruited for one of the departments with the salary of Rs. 15,000 per month. So, at the end of 4 years, 4 new professors were recruited across 4 departments. Professors who joined in May 1993 were placed in different pay scales based on their experience and qualifications, with the minimum of Rs. 15,000 per month and difference between any two pay scales is in multiples of Rs. 5,000. Each department has only one head of the department and he is paid more than the others.
