With explanation....​

Answer 1

Step-by-step explanation:

Let the C.P be x & S.P be y then 30x=24y

from (1)

x<y⇒C.P<S.P

Gain

⇒ Gain= C.PS.P−C.P ×100=( xy−x )wg

⇒( xy−1)100=( 2430 −1)100 (from (1))

⇒25%.

Answer 2

Answer:

$\sf d) \: 33 \frac{1}{3} ℅ = loss℅$

Step-by-step explanation:

The cost price of 2 pens is equal to the selling price of 3 pens = ⅔ = 100%

$\sf \frac{1}{3} = 100℅ = loss$

$\sf \frac{100}{3} ℅ = loss$

$\sf q \frac{r}{d} = 33 \frac{1}{3}$
