Answer 1

Pls mark it as brainliest..... 5 star

C.p= Rs7 1/2

Sp=Rs 8 1/3

profit = 8 1/3-71/2

25/3-15/2=50/6-45/6

= 5/6

%=5x2xloo/6x15 = 1ooo/90

= loo/9=11 1/9%

Answer 2

The gain% is $\frac{100}{9}$%.

Step-by-step explanation:

As given in question that,

Cost Price of 2 articles = 15 Rs.

Selling Price of 3 articles = 25 Rs.

We have to find the gain%.

So, C.P. of 1 articles = $\frac{15}{2}$

and S.P. of 1 articles = $\frac{25}{3}$

We know that,

gain = S.P. - C.P.

       =  $\frac{25}{3}\ -\frac{15}{2}$

       = $\frac{50\ -\ 45}{6}$

       =  $\frac{5}{6}$

gain% = $\frac{gain\times100}{C.P.}$

          = $\frac{\frac{5}{6}\times100}{\frac{15}{2}}$

          = $\frac{5}{6}\times100\times\frac{2}{15}$

          = $\frac{100}{9}$%

Therefore, the gain% will be $\frac{100}{9}$%.
