During a sale, the local outlet of the Chasm sold three times as many jeans as chinos. If they made twice as much profit for a pair of chinos as for a pair of jeans, and sold no other items, what percent of their profits during the sale came from chinos?

(A) \(16 \frac{2}{3}\) %

(B) \(20\)%

(C) \(40\)%

(D) \(60\)%

(E) \(83 \frac{1}{3}\)%

Here ;

Let the no. of chinos sold = 10

Therefore no. of jeans sold = 3 * no. of chinos = 30

Let profit from 1 pair of jeans = $1

therefore for 30 jeans, profit = $30

and the profit for a pair of chinos = 2 * profit of jeans = 2* 1 = $2

therefore for 10 chinos, profit = $20

Now total profit = $50, out of which $20 is from the sale of chinos.

Hence percentage of profit from chinos = \(\frac{20}{50} = 40%\)
