Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x) 
y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.
 Profit % = |

x | x 100 |  % = 100% |

Why here 2y-x is done? As we are only doubling selling price which is y.

= S.P - C.P = PROFIT/100%
= 2X- 3X =1X/100%
= X = 1/100
=100%.
= 2X- 3X =1X/100%
= X = 1/100
=100%.

If selling price doubled we can use only 2y?
Why all are used 2y-x?
Why all are used 2y-x?

Formula's used:
1) Profit = SP-CP.
2) Profit % = Profit/CP *100.
1) Profit = SP-CP.
2) Profit % = Profit/CP *100.
