Suppose Present Worth of Rs. 2200 is A.
2200 = (A x 110)/100.
A = (2200 x 100)/110.
A = 2000.
Gain = 2000-1950 = 50.
2200 = (A x 110)/100.
A = (2200 x 100)/110.
A = 2000.
Gain = 2000-1950 = 50.

2200 is the credit for after 1 year. So (2200/110)*100 = 2000.
So the amount might be 2000. So his gain must be 50.
So the amount might be 2000. So his gain must be 50.

2200 =interest + actual selling prize.
S.p. = x
2200 = x10/100 + x,
x = 2000.
So, that 2000-1950 = 50.
S.p. = x
2200 = x10/100 + x,
x = 2000.
So, that 2000-1950 = 50.

I also agree with sai.
I too followed the same logic.
If it is wrong could some one xplain tat?.

Think from the seller's perspective and live at present.
Then you will get Rs.50 as the answer.

If someone has sell the thing on credit then I should get interest. So profit should increase.

Correct answer should be 55 not the 50. As gain would be on the amount spent not on the 2200.

I think sai is correct because how to know whether it is think logically or do formula based.

2200 is mark price and interest is 10% then
if selling price is x
then x*1.1=2200
so x=2000
if selling price is x
then x*1.1=2200
so x=2000

Answer is wrong because,
(1950*1*10)/100 = 195.
1950+195 = 2145.
2200-2145 = 55 Rs. Gain.
(1950*1*10)/100 = 195.
1950+195 = 2145.
2200-2145 = 55 Rs. Gain.
