Answer 2

Answer:

50 rs

Step-by-step explanation:

let , the cost of books is x

and the cost of copy is y

and the cost of one book = x = 350 ------( 1 )

therefore by given data,

2x + 3y = 850

From ( 1 ) ,

2 ( 350 ) + 3y = 850

700 + 3y = 850

3y = 850 - 700

3y = 150

y = 50

therefore, the cost of copy is rs 50
