Given :  ram has 'x' marbles and his friend has two more marbles than Ram  cost of one marble is 2 rupees  

To Find :  the total cost of marbles.

Solution :

Number of Marbles with Ram = x

=> Number of Marbles with his friend  = x + 2

Total Marbles = x + x + 2

= 2x + 2

Cost of one marble = 2 Rs

Total cost of 2x +2  marbles  = (2x + 2)2

= 4x + 4  Rs
