Correct Answer: 1225


Solution : Given:
7 : 2401 :: 3 : 441 :: 5 : ?

Multiply the first number by 7 and square the resultant to obtain the second term –
Like in, 7 : 2401 → (7 × 7) 2 = 2401
And in,  3 : 441 → (3 × 7) 2 = 441
Similarly, follow the same pattern for  5 : ? → (5 × 7) 2 = 1225

So, the required missing term is 1225. Hence, the fourth option is correct.
