(B) Let the cost price be $CP$ and the initial selling price be $SP$. Let the initial profit be $P$.We know that $P = SP - CP$ $....(i)$According to the problem,when the selling price is doubled $(2SP)$,the profit becomes $3P$.So,$2SP - CP = 3P$ $....(ii)$From equation $(i)$,we have $SP = P + CP$.Substitute this into equation $(ii)$:$2(P + CP) - CP = 3P$$2P + 2CP - CP = 3P$$CP = P$Since $CP = P$,the profit percentage is calculated as:Profit $\%$ $= (P / CP) 	imes 100 = (CP / CP) 	imes 100 = 100 \%$.

If the selling price is doubled,the profit triples. Find the profit percent.
