Question

A pen and a notebook cost #240 together four pens cost the same as five notebooks. find the cost of each

Answer 1

Step-by-step explanation:

Let,

the price of one pen be x

Price of one pen+ price of one notebook= ₹270

x+price of one notebook= ₹270

Price of one notebook= ₹ 270-x

A/Q,

4x = 5(270-x)

4x = 1350-- 5x

4x = 1350-5x

4x+5x = 1350

9x= 1350

x= 150

Therefore cost of one pen =X = 150

cost of one notebook = 270 - x

= 270-150

= 120
