Answer 2

Step-by-step explanation:

Given:

The cost of 16 pens is Rs 152.

Solution:

First ,we have to find the cost of 1 pen.

To find out : We have to divide the total cost of pens by the total number of pens that are given in our question.

• Number of pens = 16
• Cost of 16 pens =Rs  152

      ∴ The cost for a single unit of pen is :

            ⇒   Cost of pens /number of pens

            ⇒  152/16

            ⇒Rs 9.5(the cost of one pen).

Second, we have to find out the cost of given units i.e 28 pens.    

To find out : We have to multiply the given unit by the cost of one unit of pen.

• Number of pens = 28

• Cost of one pen =    Rs 9.5    

∴ The cost for  28 units of  pens are :

     ⇒Cost of pens × Number of pens

     ⇒   28 ×  9.5

      ⇒ Rs 266.

Hence, the cost of 28 pens is Rs 266.
