aaa the right answer is.
Step-by-step explanation:
ruppee 266.
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.
