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
