Question

The price of a pen and pencil together is 10 rupees. The price of a pen and 5 pencils is 22 rupees. What is the price of each ?​

Answer 1

Answer:

Price of Pen = ₹7

Price of Pencil = ₹3

Step-by-step explanation:

Let Price of Pen be ₹x

and,

Price of Pencil be ₹y

According to question,

x + y = 10 _____(1)

x + 5y = 22 ____(2)

Subtracting equations

-4y = -12

y = -12/-4

y = 3

Putting value of y in eq. 1

x + y = 10

x + 3 = 10

x = 10 - 3

x = 7

Price of Pen = ₹x = ₹7

Price of Pencil = ₹y = ₹3
