Step-by-step explanation:
Let,
Price of each pen be rs.x and price of each pencil be rs.y.
Rajan had 2 pens and 2 pencils
=> Cost of 2 pens = rs.2x
=> Cost of 2 pencils = rs.2y
Ramkumar had 4 pens and 1 pencil
=> Cost of 4 pens = rs.4x
=> Cost of 1pencil = rs.y
Total bill amount of Rajan and Ramkumar
= 2x+2y+4x+y
= rs.6x+3y
