Total number of agents in Jan =2
Total number of agents in June = 4

Total sales in Jan = 2 'units'
Total sales in June = 8 'units'

Thus PER AGENT, % increase = [(8/4)-(2/2)] /(2/2) *100 = 100% increase. Thus B is the correct answer.

In January, the dealership has 2 agents and sales of $200,000, or $100,000 per agent.
After adding two more agents, 4 agents on the sales force for June and sales of $800,000 or $200,000 per agent ($800,000/4).

Percent Difference = ($200,000 – $100,000) / ($100,000)= 1 or 100%.

Total sales in Jan = 2 units
Total number of agents in Jan =2
Sales per Agent in Jan = 2/2 = 1 unit


Total sales in June = 8 units
Total number of agents in June = 4
Sales per Agent in June = 8/4 = 2 unit


% Increase = [(Final Value - Initial value)/Initial Value]*100

i.e. % increase = [(2 - 1) / 1]*100 = 100%

Answer: Option B

800score Official Solution:

(B) In January, the dealership had 2 agents and had sales of $200,000, or $100,000 per agent. An agent was added to the sales force in March (making 3) and then one more was added in May (making 4). This leaves 4 agents on the sales force for June, when the dealership sold $800,000 or $200,000 per agent ($800,000/4). We can find the percent difference by dividing the difference between the two per-agent amounts by the per-agent amount in January:
Percent Difference = ($200,000 – $100,000) / ($100,000)= 100,000 ÷ 100,000 = 1 or 100%. The correct answer is choice (B).

The trap answer is choice (D). $200,000 per agent is double $100,000 per agent. But remember that the question asks for the percent increase. $200,000 represents 200% of $100,000, but only 100% more than $100,000.
