Two merchants sell, each an article for Rs.1000. If Merchant A computes his profit on cost price, while Merchant B computes his profit on selling price, they end up making profits of 25% respectively. By how much is the profit made by Merchant B greater than that of Merchant A?
A) Rs.66.67
B) Rs. 50
C) Rs.125
D) Rs.200

SP = Rs. 1000.

For A, Profit = 0.25 C.P. = x.
So, SP = CP + x = Rs. 1000,
5x = Rs. 1000
x = Rs. 200.

For B, Profit = 0.25 S.P. = Rs. 250.

So, difference in profit = Rs. 250 - Rs. 200 = Rs. 50.
i think its somehow wrong according to me
for A

1000-xa=.25xa

xa=800

for B

1000-xb=250

xb=750

so difference comes as 50 rs.

plz check sir...
What's xa?
