(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)
(9, 63, 7)
(27, 189, 21)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. (45, 315, 35).
(9, 63, 7) → 9 × 7 = 63; 63 ÷ 9 = 7
(27, 189, 21) → 27 × 7 = 189; 189 ÷ 9 = 21
Similarly, (45, 315, 35) → 45 × 7 = 315; 315 ÷ 9 = 35
