Answer 2

Answer:

(4) ₹ 600

Step-by-step explanation:

let the value of one pen, one pencil and one eraser be x,y and z respectively

then,

according to the question

3x+2y+4z=92 ...(1)

8y+16z=68

implies that , 2y+4z=17. (take 4 common and cancel)

putting the value of 2y+4z in eqn 1

we get,

3x+17=92

or, 3x=92-17=75

or, x=75÷3= ₹25

therefore price of one pen = x= ₹25

and , price of 24 pens =24x = ₹24×25= ₹600
