- Let the C.P. be x and the S.P. be y
So the profit is (y - x) ---------------------------- (1)
Now, the S.P. is doubled. So the new S.P. = 2y
The new profit = (2y - x)
Given that when S.P. is doubled, profit increases 3 times
=> New profit = 3 * old profit
=> (2y - x) = 3(y - x)
=> y = 2x
So, the profit = (y - x) = (2x - x) = x
% profit = (x/x∗100)% = 100% - 7 years agoHelpfull: Yes(5) No(0)
- Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x)
Therefore, y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
Profit % = (x/x)*100 = 100% - 6 years agoHelpfull: Yes(2) No(0)
