Correct Answer - Option 4 : 55, 110

By formula,

HCF × LCM = Product of the two numbers

55 × 110 = Product of the two numbers

⇒ 6050 = Product of the two numbers

1) 11, 55 → Product of the two numbers = 11 × 55 = 605 ≠ 6050

2) 11, 110 → Product of the two numbers = 11 × 110 = 1210 ≠ 6050

3) 10, 55 → Product of the two numbers = 10 × 55 = 550 ≠ 6050

4) 55, 110 → Product of the two numbers = 55 × 110 = 6050 = 6050

Therefore, the two numbers are 55 and 110.

Hence, ‘**55, 110**’ is the correct answer.
