Solution by Ahmad hassan :
Actually, the question is this.
If a person sells his car in 50000 rupees and got 17% profit. What will be the profit in percentage if he sold this car in 47000 rupees?
Solution
Profit = 17 %
Sp of car = Rs 50000
Cp = sp/1 + .profit percentage
Cp = 50000/1+.17
Cp= 50000/1.17= Rs 42735.04
Now he wants to sell at Rs 47000
New sp = Rs 47000
Profit sp-cp = 47000-42735.04 = Rs 4264.96
Profit % = profitx100/cp
Profit % = 4264.96×100/42735.04 = 9.98 %
New profit % = 9.98

Solution by Vicky :
total sold price with 17% profit =50,000 (Including 17% profit)
now lets break this 50,000
50,000=X(original cost of car)+0.17x(17% profit) :- x is supposed cars original price
50,000=x+0.17x
x=50,000/1.17 (By taking x common)
x=42,735 (which is Original cost of car)
now again his is selling his damn car at Rs 47,000, that means his profit this time will be
47,000-42,735(original amount of car we just calculated above)=4265 (profit this time)
now calculate the percentage of this above calculated Profit with simple formula
4265/42735*100= 9.98% (Answer) cheers
