Select the option that is related to the third number in the same way as the second number is related to the first number.
11 : 265 :: 20 : ?
Answer & explanation
Correct answer: option 2
The pattern followed is,
11: 265 → 11: 112 + (11 + 1)2
⇒ 11 : 121 + 144
⇒ 11 : 265
Similarly,
20 : ? → 20 : 202 + (20 + 1)2
⇒ 20 : 400 + 441
⇒ 20 : 841
