Answer :

Let

Total number of story books = x
And
Total number of text books = y

So from first condition we get

y = 2x + 2

y - 2x = 2 ---------------- ( 1 )

And from second condition we get

y + 4 = 4x

y - 4x = - 4 ------------------- ( 2
)

now we subtract equation 2 from equation 1 , we get

2x = 6

x = 3 , Substitute that value in equation 1 , we get

y - 2 ( 3 ) = 2

y = 8

So,

Total number of Story books = 3
And
Total number of text books = 8 ( Ans )
