I'm not good at this shit and I TOTALLY forget how to do it!!

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

you have to solve it this way

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

Ya, simply 12+15=27

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

easiest way to do it is always write the equations of what you know from the sentences then work the equations

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

I looked at it this way:


Eli----(+15)----Pat----(+12)----Amal/Martine

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.

make a picture in your head. Put Eli first in line...
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!
