Question:
A person sold a horse at a gain of 15%. Had he bought it for 25% less and sold it for Rs. 600 less, he would have made a profit of 32%. The cost price of the horse was:

Option A):
Rs. 2,750
Option B):
Rs. 3,750
Option C):
Rs. 2,250
Option D):
Rs. 3,250

Correct Answer is Option B):
Rs. 3,750

Explanation:
Let the original CP = Rs. X.
Hence, SP= 115x/100 = Rs. 23x/20
New, CP = 75x/100 = 3x/4
New SP = (132/100)*3x/4 = Rs. 99x/100;

According to the question,
(23x/20)-(99x/100)= 600
Or, (115x-99x)/100 = 600
16x = 600*100
X = 600*100/16 = Rs. 3750.
