Question:

Select the option in which the numbers share the same relationship in set as that shared by the numbers in the given sets. (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)

(15, 13, 56)

(17, 11, 168)

Options:

(15, 11, 114)

(23, 21, 78)

(20, 14, 204)

(22, 16, 238)

Correct Answer:

(20, 14, 204)

Explanation:

(15, 13, 56)

(17, 11, 168)

THE LOGIC FOLLOWED HERE IS :

( FIRST NUMBER + IIND NUMBER ) × (FIRST NUMBER - IIND NUMNER ) = IIIRD NUMBER

AS

( 15  + 13 ) × (15  -13) = IIIRD NUMBER

28 × 2 = 56

AND

( 17  + 11 ) × (17  -11) = IIIRD NUMBER

28 × 6 = 168

SIMILARLY

(20, 14, 204)

( 20   + 14 ) × (20 -14) = IIIRD NUMBER

34 × 6 = 204
