The 2200 at the credit of 1 year means after one year, he gets 2200 so we have to find present value at which he sells watch and then subtract it from 1950.
So 2200= p + S.I.
S.I= 2200-p.
2200-p = (p*10*1)/100.
p=2000.
Therefore profit =2000-1950 = 50rs.
So 2200= p + S.I.
S.I= 2200-p.
2200-p = (p*10*1)/100.
p=2000.
Therefore profit =2000-1950 = 50rs.

CP(cost price) = 1950.
SP(selling price) = x.
After 1 year total amount = 2200/- And rate(r) = 10%.
Simpe interest = (P*R*T)/100.
2200 = [(x*r*t)/100] + x.
2200 = x[(10*1)/100 + 1].
x = (2200*100)/110.
x = 2000.
Gain = sp - cp.
Gain = 2000 - 1950.
Gain = 50.
SP(selling price) = x.
After 1 year total amount = 2200/- And rate(r) = 10%.
Simpe interest = (P*R*T)/100.
2200 = [(x*r*t)/100] + x.
2200 = x[(10*1)/100 + 1].
x = (2200*100)/110.
x = 2000.
Gain = sp - cp.
Gain = 2000 - 1950.
Gain = 50.

The answer given here 50 is wrong it should be 55, Because Seller in Investing 1950 as to incur the cost at 10%(i.e. 195) and the buyer is paying 2200 after a year.
So, the sellers cost is 1950+195 =2145 and hence his gain in the transactions is 2200-2145 =55.
So, the sellers cost is 1950+195 =2145 and hence his gain in the transactions is 2200-2145 =55.

Here c.p = 1950.
If the rate of interest is 10% per annum.
10% of c.p= 195.
total c.p = 2145.
s.p = 2200.
profit = s.p - c.p
2200 - 2145 = 55.
So, profit = 55.
If the rate of interest is 10% per annum.
10% of c.p= 195.
total c.p = 2145.
s.p = 2200.
profit = s.p - c.p
2200 - 2145 = 55.
So, profit = 55.

Amount = 2200, at interest 10%, for a credit period of 1 year,
Amount = (p*n*r)/100 + p,
2200 = (p * 1 * 10)/100) + p,
1.1 p = 2200.
p = 2000 (selling price),
profit = 1950 - 2000,
profit = 50.
Amount = (p*n*r)/100 + p,
2200 = (p * 1 * 10)/100) + p,
1.1 p = 2200.
p = 2000 (selling price),
profit = 1950 - 2000,
profit = 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.

Why 55 is wrong?
Because according to the people who are that's not true. We cannot predict the original price of the watch in future. Maybe it can be a loss!. But definitely, we can comment on present profit. So giving a profit after 1 year implicitly invalid whether it's 50, 55 or 30 until and unless there is not mention of a rate with which original price would have increased.
