Select the set in which the numbers are related in the same way as are the numbers of the following set.
(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)
(5, 4, 405)
(7, 3, 500)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (4, 1, 125)
Logic used : ( First number + Second Number )2 x 5 = Third Number
⇒(5, 4, 405)
( 5 + 4 )2 x 5 = 81 x 5 = 405
⇒(7, 3, 500)
( 7 + 3)2 x 5 = 100 x 5 = 500
Similarly,
⇒(4, 1, 125)
( 4 + 1)2 x 5 = 25 x 5 = 125
Hence, (4, 1, 125) is the correct answer.
