A pen cost twice as much as much as pencil.if the cost of 5 pencil and 6 pencil is RS 96,find the cost of 6pen and 5pencils.

Answers

Using algebraic equations:

Cost of 6 pen = Rs 72

Cost of 5 pencils = Rs 30.

Total cost = 30 + 72 = Rs 102.

How to Apply Algebraic Equation?

Let the x be used to represent cost of pencil. Therefore, we would represent the situation using algebraic expressions as shown below:

Cost of pencil = x

Cost of pen = 2x

Cost of 5 pen = 5 × 2x = 10x

Cost of 6 pencils = 6 × x = 6x

We are given that the total cost of 5 pens and 6 pencils is Rs 96, therefore, the following algebraic equation would be written to find the value of x:
