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
