21 441 : 462 :: 841 : ?Answer: Option [D]Solution:
As, 441 + √(441) = 441 + 21 = 462
Similarly
841 + √(841) = 841 + 29 = 870
Answer: Option [D]Solution:
As, 441 + √(441) = 441 + 21 = 462
Similarly
841 + √(841) = 841 + 29 = 870
Answer: Option [B]
Solution:
As, 3 and 34 = 81
Similarly
6 and 64 = 1296
Answer: Option [C]
Solution:
16
As, 72 - 1 = 48 and 82 - 1 = 63
Similarly
52 - 1 = 24 and 62 - 1 = 35
Answer: Option [B]
Solution:
25 = 52, one number less than 5 is 4 and 42 = 16
25 - 16 = 9 or 52 - 42 = 9
Similarly
49 = 72. So, 72 - 62 = 13
Answer: Option [A]

The next prime number of 13 is 17. Similarly, the next prime number of 23 is 29.
Answer: Option [D]
Solution:
53 = 125 and 52 = 25
Similarly
43 = 64 and 42 = 16
Answer: Option [C]
Solution:
Second number, divided by 11, gives the first number.
33 ÷ 11 = 3
Similarly
3333 ÷ 11 = 303
Answer: Option [C]
Solution:
√(2500) = 50, 2500 - 50 = 2450
Similarly, √(3025) = 55, 3025 - 55 = 2970
Answer: Option [A]
