Together, Andrea and Brian weigh p pounds; Brian weighs 10 pounds more than Andrea. Brian and Andrea's dog, Cubby, weighs p/4 pounds more than Andrea. In terms of p, what is Cubby's weight in pounds?
(A) p/2 - 10
(B) 3p/4 - 5
(C) 3p/2 - 5
(D) 5p/4 - 10
(E) 5p - 5
(A) p/2 - 10
(B) 3p/4 - 5
(C) 3p/2 - 5
(D) 5p/4 - 10
(E) 5p - 5
I have formed the following algebric equations for the above, but I can't seem to get to the answer.
A + B = p
B = A + 10
C = p/4 + A
However, if I use actual numbers and plug the answer, the question can be solved. What am I missing?
Thanks

guys, the correct answer is B
I know the question is poorly written - but hey..i copied it from a 'reputed' GMAT prep book.
But the trick is the word "weighs"....meaning only cubby weighS P/4 + A
Read the question as (Brian + Andrea)'s dog, cubby weighs...
And thanks for the help

pretty straightforward.
a + b = p
b = a + 10
c = p/4 + a
there is no b in the choices. this means we have to get rid of it.
a+ (a+10) = p
2a = p -10
a = p/2 - 5
c= p/4 + a
c= p/4 + p/2 - 5
c = p/4 + 2p/4 - 5
c = 3p/4 - 5
a + b = p
b = a + 10
c = p/4 + a
there is no b in the choices. this means we have to get rid of it.
a+ (a+10) = p
2a = p -10
a = p/2 - 5
c= p/4 + a
c= p/4 + p/2 - 5
c = p/4 + 2p/4 - 5
c = 3p/4 - 5
