I couldn’t find that. I found bb’s post on directory that led me to this now. I hope this is what you meant. gmat-ps-question-directory-by-topic-difficulty-127957.html

Hi everyone, does anyone know how to do this: " last year a company gave bonuses to a number of employees but only in the three amounts $750, $1500, $7350. If the total amount of the bonuses was $64800, and each of the three amounts was given to at least one employee, what is the fewest number of bonuses that the company could have given to employees last year?

Yes, I guess so
750 - 2
1500 - 3
7350 - 8

A bit lengthy process with trial and error...

750x + 1500y + 7350z = 64800
Reduce the equation by dividing by 150

You get
5x + 10y + 49z = 432

Minimum value of x,y,z is 1
For x+y+z to be min we will have to keep z highest

5(x+2y) = 432-49z
RHS is multiple of 5
Highest z = 8

Substitute and you get x+2y = 8
This gives x= 2 and y = 3

my question is that what is the coordinate of the S point

in a video i saw that the instructor said 45 degree in which according

(12,9) are coordinates for S

the way i want to know it

there is a equation of a line given

12,15 ,just put x =12 in equation ,u will get Y =15 , and the area will be = 1/2 ×b×h = 1/2* 9*3 = 27/2

Heyy thanks so much! How did you arrive at solutions for x and y from x +2y=8 though?

I am assuming equation is y-x=3 as before 3 it’s blurr so I think it’s equal to

You can do it orally also , It’s says fewest number of bonuses, so how can we do that - let’s put maximum number in 7350 so if 7350 given to 10 =73500 but it’s more ,when given to 9 then also it’s more ,so only possible is 8 . Find 7350 ×8 ,and then subtraction it from 64800 and remaining amount u should divide into 750 and 1500 multiples .

And only possible way to divide remaining amount is giving 750 to two people and 1500 to three

Now how can u get this , remember it should be a multiple of 750 and 1500 ,so u can check combination of 750 and 1500 multiples and add them to get a value equal to remaining amount . It may sound like lengthy to you right now ,but originally it will take around 15-20sec ,which will be helpful in exam

wrong. the ans is .5*9*9

Hey ,

What all to cover in co ordinate ?

Slopes , co ordinates , reflection, anything else ?

Is co-ordinate geometry in syllabus?

Lemme Know if what I used was correct.
I divided total with highest value first- 64800 by 7350, it gave me 8 and a remainder of 6000 which I again divided by next highest bonus amount -1500, it gave me the count 4 but since we have to use all bonus amounts at least once, I reduced the 1500$ bonus count from 4 to 3 and remaining bonus was of 750 which gets the count 2 since I reduced 1 from 1500 count. so total - 8+3+2=13!!

Yes that’s what I wrote above ..its correct

And less time.taking

loved this approach
