Correct Answer: 361441529


Solution : Given:

1 x 3 x 5=1925

Here in the equation, we have–

(1)² = 1 , (3)² = 9 , (5)² = 25

⇒ 1925 .

7 x 9 x 11= 4981121

In this equation, we have–

(7)² = 49 , (9)² = 81 , (11)² = 121

⇒ 4981121

Similarily, the value of –

19 x 21 x 23 ⇒ (19)² = 361 , (21)² = 441 , (23)² = 569

⇒ 361441569

Hence, option fourth is correct.
