Question 1089344
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 {{{SP= 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)}}}

=> {{{2y - x = 3y - 3x}}}

=> {{{y = 2x}}}

So, the {{{profit = (y - x) = (2x - x) = x}}}

{{{profit_percent =(x /x) * 100)}}}% = {{{100}}}%
