Answer:I’ll explain only maths book.

Suppose there are 100 books.

So, out of 100%, there are 25% maths books.

Out of 100, there will be 25.

100 → 25 maths books (given)

1 → 25/100 = ¼ maths books

1200 → 1200 × ¼ = 300 maths books.

Same as, for science,

100 → 35

1 → 35/100

1200 → 1200 × 35/100 = 420

For others, using %es,

100 → 40

1 → 4/10

1200 → 1200 × 4/10 = 480.
