Answer 2

Answer:

Price of Pen= Rs8, price of pencil=Rs.1

Step-by-step explanation:

Let price of pen be x

and price of pencil be y

According to question,

4x+y=34 ------(1)

& x+4y=16 -----(2)

multiplying eq (2) by 4, we get,

4x+16y=64 ----(3)

(3)-(1) gives,

15y=30

y=2

put y=2 in (1),

4x+2=34

4x=32

x=8

Therefore, price of pen=Rs.8

and price of pencil be Rs.2
