(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 /deleting /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)
(84, 28, 4)
(147, 49, 7)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. (231, 77, 11).
(84, 28, 4) → 4 × 7 = 28; 4 × 3 × 7 = 84;
(147, 49, 7) → 7 × 7 = 49; 7 × 3 × 7 = 147;
Similarly, (231, 77, 11) → 11 × 7 = 77; 11 × 3 × 7 = 231;
