Answer:

pen's cost is 10 rupees

pencils 'cost is 7 ruppes .

so , let cost of pen be 10x

cost of pencil be 7x

then , it would be written as , As per the question

10x+7x=85

17x=85

X= 85/17

X= 5

From above solution we get that the total cost of pen and pencil is purchased how much time.

now , we can find how many pen and pencil were purchased.

let's start it, Step by step

let pen's cost be X = 10 rupees

and pencil's cost be y= 7 rupees

so we can write it

like that

(X+Y)×5= 85

so our final answer is

(X+Y)×5=85.

LET'S CHECK THAT

(X+Y)×5=85

here X= 10 ₹

Y= 7 rupees

by putting values on equation

(X+Y)×5=85

(10+7)×5=85
