Answer 2

Answer:

pen = 10rupees

pencil=3 rupees

Step-by-step explanation:

The price of one pen is x and price of one pencil is y

so 4x+3y=49.............(i)

and 9x+3y=99............(ii)

substract eqn(i) from eqn(ii) then

5x=50

x=10

then putting the value of x in eqn( i)

then y=3

so the cost of one pen is 10 and the cost of one pencil is 3.
