Question

If sp is doubled the profit triples. find the profit percent

Answer 1

Let the initial profit = x

profit, x = SP - CP
______________

If sp is doubled the profit triples.

Profit = 2SP - CP = 3x

=> SP + SP - CP = 3x

=> SP + (SP - CP) = 3x

=> SP + x = 3x

=> SP = 2x
_________________
From the beginning, we saw that

x = SP - CP

=> x = 2x - CP

=> CP = 2x - x

=> CP = x
________________

So initial profit percent = Profit/CP × 100

=> profit % = x/x × 100 = 100%
