40% of 540 is 216. Then the company hires 60 people. 15% of the 60 are part time. This amounts to 9. Add 216 + 9 = 225. This is an increase from 216. So the answer is D (9/216*100)

There's actually a percent decrease in PT employees, so I don't understand what the question is asking. The question is asking by what percentage the number of parttime employees will increase. Original number = .4*540 = 216. Additional parttimers = .15*60 = 9. % increase = (9/216)*100 = 4 1/6%.

The GMAT would likely make it crystal clear what was being asked: By what percent did the number of parttime employees increase? By what percent did the ratio of part time employees to the total number of employees decrease? Hope this helps!

Hello !
I have just solved the problem and I wonder why there is a discrepancy between the actual answer and the answer choice D.
To me (9/216)*100 = 4,16666 which is not equal to 4 1/6 %
Or maybe it is because 4 1/6% actually means (4 + 1/6)% and not (4 * 1/6)% ? Is it an american way of writing decimal numbers (am foreigner) ?

Hi i have a small doubt it may be silly but iam confused,thanks to help me.
Actually 9 members were added to part time job.So the count has increased from 216 to 225(216+9). So i thought 1st we should find 225 is what percent of 600  40%(the original) So that we can get the increase in the percent. Can you plz tell me where did i go worng:(

yea i did the same mistake first... was getting 225/600 as 37% but since the question asked increase..
i reverted to the methods suggested above... if the overall percentage was asked.. i think we could have attempted such a method... but since the q asks percentage increase of part time employees, 9/216*100 i the approriate calc

With 540 of employees, part time employed are 40%  216 and 60% are full time  324. After hiring 60 new employees, 15% are part time i.e. 9 and 51 are full time.
Percent increase in the part time employees are (9/216)*100 = 25/6
My answer is D.

A) 1 2/3 % B) 2 2/3 % C) 4 % D) 4 1/6 % E) 9 % Total employees = 540 ; Part time = 216 ; Full Time = 324 Quote: If it hires 60 new employees, 15% of whom are employed part time, Total employees = 60 ; Part time = 9 ; Full Time = 51 After recruitment of 60 New employees  Total employees = 600 ; Part time = 225 ; Full Time = 375 Quote: What will be the percent increase in part time employees? % Increase = \(\frac{9}{216}*100\) = \(4\frac{1}{6}\) Hence, answer will be (D)

A) 1 2/3 % B) 2 2/3 % C) 4 % D) 4 1/6 % E) 9 % Total employees \(= 540\) Part time employees \(= 40\)% of \(540 = \frac{40}{100}* 540 = 216\) Total number of new hires \(= 60\) Part time employees in new hires \(= 15\)% of \(60 = \frac{15}{100} * 60 = 9\) % increase of part time employees \(= (\) Difference of part time employees \(/\) Original number of part time employee\() * 100\) Difference of part time employees is the increase of part time employee. That is \(= 9\) Therefore Required percentage \(= \frac{9}{216} * 100 = 4 \frac{1}{6}\) % Answer D
