$\:\:$

• May bought bananas at rupees 120 a dozen

• She sold the bananas for rupees 15 each

$\:\:$

$\sf\large\bold{\orange{\underline{\blue{ To \: Find :-}}}}$

$\:\:$

• Her profit

$\:\:$

$\sf\large\bold{\orange{\underline{\blue{ Solution :-}}}}$

$\:\:$

$\underline{\bold{\texttt{Cost price :}}}$

$\:\:$

➠ $\sf \dfrac { Total \: money \: used \: in \: buying } { Total \: number \: of \: articles }$

$\:\:$

• Total money used in buying 1 dozen banana = 120

• Total number of banana = 12

$\:\:$

➜ $\sf \dfrac { 120} { 12 }$

$\:\:$

➜ 10

$\:\:$

• Hence cost of 1 banana is Rs 10

$\:\:$

$\underline{\bold{\texttt{Selling price :}}}$

$\:\:$

Let the total money got by selling bananas be "x"

$\:\:$

• The total money got by selling 1 dozen banana = x

• Total number of bananas = 12

$\:\:$

➠ $\sf \dfrac { Total \: money \: got \: by \: selling } { Total \: number \: of \: articles }$

$\:\:$

➜ $\sf \dfrac { x } { 12 }$

$\:\:$

Given that the selling price of 1 banana is Rs 15

$\:\:$

So,

$\:\:$

➜ $\sf \dfrac { x } { 12 } = 15$

$\:\:$

➜ x = 12 × 15

$\:\:$

➜ x = 180

$\:\:$

• Hence May got Rs 180 by selling her bananas

$\:\:$

To find the profit or loss we will subtract Total money used in buying 1 dozen banana by The total money got by selling 1 dozen banana

$\:\:$

So,

$\:\:$

➜ 180 - 120

$\:\:$

➨ 60

$\:\:$

The positive sign indicate that it is a case of profit

While if we got a negative sign here then it would be a case of loss

$\:\:$

• Hence May got profit of Rs 60
