How do I do this kind of question?
Posted 07 March 2011 - 08:05 AM
Amal distributed 12 more questionnaires than Pat. Eli
distributed 15 fewer questionnaires than Pat. Martine
distributed the same number of questionnaires as Amal.
What is the difference between the number of
questionnaires distributed by Amal and the number
distributed by Eli?
(1) 15 (2) 27 (3) 3 (4) 13 (5) None of the above

Pat is equal to A
so Amal is A+12
Eli is A-15
Martine is equal to Amal, so not really part of the equation
so just add the two numbers together

they added some words to sort of make it less obvious, but that is it...

A + 12 = P
E - 15 = P
M = A (but don't need this one)
The question you want answerd is A + ?? = E
Then you can fill in the equations trying to get the same letters into an equation
So since A + 12 and E- 5 = P you can say-- A + 12 = E -15
then you can isolate one of the letters. I will pick E so I have to do the same thing to both sides (add 15 to both sides) The equation now becomes A + 12 + 15 = E
So A + 27 =E

Edited b/c I couldn't get Amal and Martine's names to line up evenly in the same column. I ended up putting their names together instead.

Eli_____+15___ Pat____+12____ Amal
So 15+12= the difference between Eli and Amal.
but my brain works weird so even though this makes complete sence to me you might look at it and see how weird my brain works LOL and I also do Logic Puzzles at night while listening to audiobooks... I can do stuff like that but I suck at spelling... go figure!
