225 books could be stocked in the shelf.
Explanation:
The thickness of each book = 3 cm.
∴ The thickness of 150 books together = (150×3) cm
= 450 cm
The length of the shelf = total thickness of the books = 450 cm.
∴ The length of the shelf is 450 cm.
∴ If the thickness of each book would be 2 cm then the number of books could be stocked in the shelf _
(450/2) books
= 225 books.
∴ 225 books could be stocked in the shelf.

Answer:
Step-by-step explanation:
Books Thickness
150 3 cm
x 2 cm
inverse variation
x1 : x2 :: y2 : y1
150 : x :: 2 : 3
150 × 3 = 2x
150 * 3 / 2 = x
75 * 3 = x
225 = x
x = 225
