Answer 2

Answer:

Cost of one pen = Rs. 10

Cost of one pencil = Rs. 0

Step-by-step explanation:

Let, cost of one pen be Rs. X and cost of one pencil be Rs. Y.

A/q,

6X + 4Y = 60

or, 3X + 2Y = 30

or, Y = (30 - 3X) / 2 ____(i)

Again, 4X = 40

or, X = 10

Putting Value of X in equation (i),

Y = (30 - 30) / 2

or, Y = 0

I would like to recommend you to check the question again because Cost of each pencil is Rs. 0 i.e., it is free.
