Detailed Solution

Concept- In order to solve the given question, we will use the HCF and LCM .
Here,

Number of science books = 280

Number of math books = 300

Then,

HCF of both 280, 300 = 20

Therefore,

Number of stacks of science books = \frac{280}{20} = 14

Number of stacks of math books = \frac{300}{20} = 15

So, the correct answer is 14,15.
Hence, the correct option is 1.
