Step-by-step explanation:

Given -

The cost of pencil is Rs5 more than the cost of eraser.

Cost of 8 pencils and 10 eraser is 130

To Find -

The cost of pencil is Rs10 True or False

Let y be the cost of erasers.

According to the question :-

Cost of a pencil is 5Rs. more than the cost of an eraser.

It means,

Cost of a pencil is y + 5

Now,

Cost of 8 pencils and 10 eraser is :

→ 8(y + 5) + 10y = 130

→ 8y + 40 + 10y = 130

→ 18y = 90

→ y = 5

Hence,

The cost of eraser is Rs 5

And

The cost of pencil is y + 5 =

→ 5 + 5

→ Rs 10
