Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their 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.)
(7, 2, 70)
(6, 4, 120)

Option 1: (3, 8, 120)

Option 2: (13, 4, 208)

Option 3: (5, 9, 270)

Option 4: (11, 6, 143)

Correct Answer: (3, 8, 120)


Solution : Given:
(7, 2, 70); (6, 4, 120)

Multiply the first and the second number then multiply the resultant number by 5 to obtain the third number in the given set of numbers –
⇒ (7, 2, 70)→(7 × 2) × 5 = 14 × 5 = 70
⇒ (6, 4, 120)→(6 × 4) × 5 = 24 × 5 = 120
Let's check the options –

First option: (3, 8, 120)→(3 × 8) × 5 = 24 × 5 = 120
Second option: (13, 4, 208)→(13 × 4) × 5 = 52 × 5 = 260 ≠ 208
Third option: (5, 9, 270)→(5 × 9) × 5 = 45 × 5 = 225 ≠ 270
Fourth option: (11, 6, 143)→(11 × 6) × 5 = 66 × 5 = 330 ≠ 143

So, only the first option follows the same pattern as followed by the given set of numbers. Hence, the first option is correct.
