Correct Answer - Option 4 : 165

**Calculation:**

HCF of these number is 15

So, let assume that number is 15x

and other number is 15 y

According to question

⇒ 15x × 15y = 6300

⇒ xy = 28

Factors of 28 are

28 × 1 = 28

14 × 2 = 28

7 × 4 = 28

So,

Numbers are

15 × 7 = 105

15 × 4 = 60

∴ Sum of numbers is 105 + 60 = 165

The correct option is 4 i.e. 165
