Answer 2

Answer:

Rs 12.5

Step-by-step explanation:

Let Cost Price of pen be x and Cost Price of pencil be y.

So, 20x + 16y =360

Dividing by 4

= 5x + 4y = 90 A

Profit on 1 pen 0.25x

Profit on 1 pencil 0.40y

So, 20*0.25x + 16*0.4y = 120

= 5x + 6.4y =120 B

Solving equations A and B,

2.4y = 30

y = 12.5
