3X/4=225000$
X=300000$
0.7×300000=210000$
225000-210000=15000$
Option A

(E) $90,000



SP = 0.75*CP of 1st house.
&
CP of new house = 0.7*CP of 1st house
It is then given that SP = 225,000
Therefore,
CP of 1st house = 225,000/0.75 = 300,000
Now,
CP of new house = 0.7* 300,000 = 210,000

Net gain = SP of 1st house - CP of 2nd house = 225,000 - 210,000 = 15,000 [A]

(A) $15,000

(B) $25,000

(C) $60,000

(D) $75,000

(E) $90,000


We can use the following equation to determine the cost of Karen’s house:

0.75n = 225,000

n = 300,000

She bought her new house for 0.7 x 300,000 = $210,000

Thus, her net gain was $15,000.

Answer: A
