Question

The price of 6 pencil and 9 pen is 120 rupees and the price of 6 pencil and 15 pen is 180 rupees what is the price of pencil and the price of pen?

Answer 1

Step-by-step explanation:

If, we assume that pencil be x and pen be y.

According to the question,

6x + 9y = 120 ...(1)

6x +15y = 150...(2)

Subtract equation 1 from 2

We get,

y = 5

Then put the value of y in equation 1

We get,

x = 12.5

So the value of pencil is 12.5 and pen is 5
