Answer 2

Answer:

(c) 17

Step-by-step explanation:

To get the answer, we are supposed to subtract 3 and 7 from 275 and 330 respectively.

275 - 3 = 272 ; 330 - 7 = 323.

As we know that the greatest number divisible by two numbers is called their Highest Common Factor (HCF), we find the HCF of 272 and 323 , i.e. , 17.

Therefore, the answer is (c)17.
