(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g.13 – Operations on 13 such as adding /subtracting /multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed)
18 : 400 :: 23 : 625 :: 14 : ?
Show answer & explanation
Correct answer: A
Explanation
18 : 400 :: 23 : 625 :: 14 : ?
Just as
18 : 400
18 + 2 = 20, and 20² = 400
And
23 : 625
23 + 2 = 25, and 25² = 625
Rule: Second number = (First number + 2)²
Similarly
14 : ?
14 + 2 = 16
16² = 256
