Answer 2

Answer:

∴ The cost of $6$ bananas is Rs. $20$.

Step-by-step explanation:

• In context with question asked,
• We have to find the cost of $6$ bananas.
• It is given that, the cost of $1$ dozen banana = Rs. $40$
• To find the cost of $6$ bananas, we have to use rational method.
• As we know that, $1$ dozen banana has $12$ units.
• Let, $x$ be the cost of $6$ bananas.
• So, the required ratio is,

        $\frac{6}{12} =\frac{x}{40}$

• By cross multiplication, we get

        ∴ $6\times 40=12x$

             ∴ $12x=240$

               ∴ $x=\frac{240}{12}$

               ∴ $x= 20$

• ∴ The cost of $6$ bananas is Rs. $20$.
