See if you are assuming that 100 employees are there then
75% use laptops so 75 employees
1) 60%(75) use both so 45 employees
so by using the principle of sets 100= 75 + P -45
hence P=70
2)100=75 + P - (90/100)*P
solve this also and you'll get P
So the correct answer should be 'D' right?

{Total} = {Laptop} + {PDA} - {Both} + {Neither}. So, you'll have one more variable in each statement thus you won't be able to solve.
Next, if you solve 100=75+P-0.9*P you'll get P=250, which does not make sense.
And finally, on the GMAT, two data sufficiency statements always provide TRUE information and these statements never contradict each other but from 100=75+P-45 you get P=70 while from 100=75+P-0.9*P you get P=250, which cannot happen on the GMAT.
Hope it's clear.
Hi,
Appreciate the response. I was under the impression that if nothing has been given about the [Neither] part you can ignore it, anyway thank you! I get it now!
