Answer:

The cost of $2\frac{1}{2}$ metre of cloth is Rs. $300$.

Step-by-step explanation:

Given : Cost of $\frac{1}{3}$ metre of cloth = Rs. $40$

To find : The cost of $2\frac{1}{2}$ metre of cloth =?

Solution :

• It is given that the cost of $\frac{1}{3}$ metre of cloth = Rs. $40$
• We have to find the cost of $2\frac{1}{2}$ metre of cloth.
• Let, $x$ be the cost of $1$ metre of cloth.
• To find the cost of  $2\frac{1}{2}$ metre of cloth, first we have to use given data and have to make an equation.  

• According to given data, the equation becomes

      $\frac{1}{3} *x=40$

       ∴ $x=40*3$

       ∴ $x=120$ Rs.

• Now, the cost of $2\frac{1}{2}$ metre of cloth = $2\frac{1}{2} *120$

                                                 = $\frac{5}{2} *120$

                                                 = Rs. $300$

• ∴ The cost of $2\frac{1}{2}$ metre of cloth is Rs. $300$.
