Select the triad from the below options that has the same analogy as the following triads.
(NOTE: Operations should be perforated on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 — Operations on 13 such as adding i 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)
3 : 26 : 8
7 : 342 : 20
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4. i.e. 4 : 63 : 11.
Logic : (First Number )3 - 1 = Second Number , (First Number x 3) - 1 = Third Number
⇒3 : 26 : 8
(3)3 - 1 = 26
(3×3) - 1 = 8
⇒7 : 342 : 20
(7)3 - 1 = 342
(7×3) - 1 = 20
Similarly ,
⇒4 : 63 : 11
(4)3 - 1 = 63
(4×3) - 1 = 11
Hence ,4 : 63 : 11 is the correct answer.
