I get D. In 2 years, we have 365*2=730 days. Now, we have to find out the overall number of 20 day and 30 day 'chunks', if you will.
So, we get 730/20 = 36.5 and 730/30 = 24.3. To find what percent greater, we do (36.524.3)/24.3 = 12.2/24.3, which is approx 50%

Hi Can anyone help me with the other version of the question where the answer will be 33%. I was trapped. But i am confused in the wording of the question. I suppose we are asked to calculate the change between each...

Senior is \(\frac{1}{30}\) Junior is \(\frac{1}{20}\) for a 2 year period ( senior) 2/30 >> \(\frac{1}{15}\) for a 2 year period ( Junior) 2/20 >> \(\frac{1}{10}\) To find Junior  senior / senior * 100 {1/10}  {1/15}/ {1/15} * 100 = 50 percent

S: 1/month => 12/year => 24/2 years J: 1.5/month => 36/2 years
% of J > S in 2 years: (JS)/S*100=50%

To find Junior  senior / senior * 100
{1/10}  {1/15}/ {1/15} * 100
= 50 percent Responding to a pm: When you say Senior is 1/30, what do you mean by it? It is the rate of visit. The time of visit is 30 days. The rate is 1/30. Similarly, the rate of visit for junior is 1/20. The 2 yrs has no significance in this case. The rate stays the same for every time interval. {1/20}  {1/30}/ {1/30} * 100 = 50%

Archit If the question were: "The number of visits that a senior sales representative makes in a 2year period is approximately what percent smaller than the number of visits that a junior representative makes in the same period?", then the answer would 33%: (3624)/36=1/3=~33%. When asked "a is what percent greater/smaller than b" always put b in the denominator: (ab)/b*100. Hope it helps. I got the answer to this question correct, but the above has confused me a bit. In the question, I treated Junior as A and Senior as B, therefore (AB)/B = (3624)/24 = 50%. But in the above you say that if it were the percent that senior was smaller than junior, it would be (3624)/36 as "When asked "a is what percent greater/smaller than b" always put b in the denominator: (ab)/b*100". So if Senior is then A and Junior then B, would it not be 2436/36?

{1/20}  {1/30}/ {1/30} * 100 = 50% YOu're the best Karishma!! I performed a lengthy calculation, though not really performed the multiples and divisions but left the big numbers there for cancelations, and also realized that the number of year (1 year or 2 or whatever) does not mean anything. The rate is the same, so this question is as simple as: (3020)/20 = 50%

Anyone who want to review my solution?
2 years = 2 * 365 days = 730 days
I: senior: \(\frac{730}{30} = \frac{73}{3}\) junior: \(\frac{730}{20} = \frac{73}{2}\)
II: (junsen): \(\frac{73}{2}  \frac{73}{3} = \frac{73}{6}\)
III: change / sen: \(\frac{73}{6}/\frac{73}{3} = \frac{73}{6} * \frac{3}{73} = \frac{1}{2}\)

A. 10% B. 25% C. 33% D. 50% E. 67% number visits by seniors=730/30 and number of visits by juniors = 730/2 the difference is 73/6 (diff/no of visits by seniors) *100 = 50% note that you can assume any variable; it gives the same answer x/30 and x/20 diff = x/60 yet, you arrive at the same answer.
