Because time is of the essence, volunteers should be interviewed: a. every week with as many persons who have volunteered. b. at 10-minute intervals. c. in small groups. d. by job type.

Option D

Explanation: As time is a very important resource for every organisation and is considered as the essence of success, business organisations should manage it properly.

The interviewing process in recruitment should be done on the basis of job type. It means all the candidates that are applying for same job profile or job in the same departments should be interviewed at the same day individually. This will help the organisation to save its time.

Hence, from the above we can conclude that the right Option D.

8.08

Explanation:

Hi!

The income elasticity of demand is calculated by dividing the negative % change in demand by the % change in real income.

We calculate the negative % change in demand as:

19/20 = 0.95, a 95%

Then, the % change in real income as:

(34,000-30,000)/34,000 = 0.1176, an 11.76%

So the income elasticity of demand is:

0.95/0.1176 = 8.08

Hope it helps! :)
