Suzie has $300 more than eric has. if suzie were to give eric 10% of her money than eric wold have 2/3 of the amount suzie would then have. How much money does eric currently have (before exchanging the money)?
Saw this on a
Manhattan Prep blog and cannot find the answer anywhere!
Let S be amount Suzie has, and E amount Eric has
from first sentence, S= E + 300
from second sentence (2/3)(0.9S) = E + 0.1xS
replacing S by E+300 in the second equation, you get E=300
