• C. 7 books from Shop A
• D. 7 books from Shop B

Answer 1

Answer: (A), (D)

The correct options are
A 8 books from Shop A
D 7 books from Shop B

Rani may have bought books from either of the two shops.
If she bought books from shop A, then, number of books bought = $\frac{280}{35}=8$.
If she bought books from shop B, then, number of books bought = $\frac{280}{40}=7$.
