Given information:
- HCF of two numbers = 11
- LCM of two numbers = 609
- One of the numbers = 77
Calculating the other number:
- Let the other number be x.
- According to the property of HCF and LCM: HCF * LCM = Product of the two numbers
- Therefore, 11 * 609 = 77 * x
- Solving for x, we get x = (11 * 609) / 77 = 87
Therefore, the other number is 87, which is option B.

Given:
HCF = 11 & LCM = 609
Concept used:
Product of numbers = HCF × LCM
Calculation:
Let, 2nd number be m,
⇒ m × 77 = 11 × 609
⇒ m = 609/7
⇒ m = 87
∴ The 2nd number is 87.
