Hi all,

Hope everyone is well. I trying to find a missing number of employees and I am not sure what is a valid solution to do it..

The given problem:
Company A (type1) has 1000 employees
Company B (type1) has 250 employees
company C (type 1) has 500 employees
Company D (type1) has x employees
Company E (type 2) has 750 employees

can we find the number of employees of Company D?

Could someone please advise if there is a valid way to calculate that?

Certainly not with the information you've given to us! You'd need to tell us a lot more.

Why do you think there could be an answer?
 
One way to go from 1000 to 250 is to multiply by 0.25.
One way to go from 250 to 500 is to multiply by 2.
If we multiply 500 by "p" to get x then x= 500p.
If we multiply x by "q" we qx= 500pq= 750.
pq= 750/500= 1.5.

We could for example take p= 1 and q= 1.5.
Then we can go from 100 to 250 by multiplying by 4,
from 250 to 500 by multiplying by 2, from 500 to x= 500 by multiplying by 1, then from 500 to 750 by multiplying by 1.5.

Or we could take p= 1.5 and q= 1. The we would go from 500 to x= 750 by multiplying by 1.5 and from 750 to 750 by multiplying by 1.

But 3 times 0.5 is also 1.5. If we take p= 3 and q= 0.5 we go from 500 to x= 1500 by multiplying by 3 then from 1500 to 750 by multiplying by 0.5.

Or take p= 0.5 and q= 3. Then x= 0.5(500)= 250.

All of those are plausible- and that's just using multiplication.
