Question

if sp is triples the profit 4th times what's profit %​

let the C.P.=X and S.P. =y

so the profit = ( x-y)

now,

when the S.P. is double

new S.0. = 2y

new profit = 2y

given that when S.P. os doubled , profit increase 3 time

new profit =3× old profit

(2y-x) =3(y-x)= x

profit% = x*100/x =100% ans
