(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.)
(13, 18, 21)
(11, 25, 8)
Correct Answer: (a) (14, 33, 9)
Note: Logic: (1st num) × 3 = (2nd num + 3rd num)
(13, 18, 21) :- 13 × 3 = (18 + 21) ⇒ 39 = 39
(11, 25, 8) :- 11 × 3 = (25 + 8) ⇒ 33 = 33
Similarly,
(14, 33, 9) :- 14 × 3 = (33 + 9) ⇒ 42 = 42
