Question

If SP is doubled and profit is tripled . Find profit percent

Answer 1

let cp be x
sp be y
profit= sp - cp = y-x
now profit % =
$\frac{profit}{cp} \times 100 \\ = \frac{y - x}{x} \times 100$
$\frac{100( x - y)}{x}$
second
profit is tripled and SP doubled so
2y -x = 3(y-x)
3y-2y = 3x +x
y = 4x
profit = 4x - x = 3x
profit% =
$\frac{3x}{x} \times 100 \\ = 300$
first profit is 300%
second profit
= > y= 4x
2y = 2*4x = 8x
so profit = 8x-x = 7x
profit% =
$\frac{7x}{ x} \times 100 \\ 700\%$
700% is answer and 400% is growth

Hope it helps
