Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given 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.)
(14, 378, 9)
(18, 432, 8)
Option 1: (5, 125, 8)
Option 2: (15, 405, 9)
Option 3: (15, 305, 7)
Option 4: (11, 265, 8)
Correct Answer: (15, 405, 9)
Solution :
Given:
(14, 378, 9); (18, 432, 8)
In the given set of numbers,
multiply the first and third numbers by 3 to get the second number.
(14, 378, 9)→14 × 9 × 3 = 378
(18, 432, 8)→18 × 8 × 3 = 432
Let's check the options –
First option:
(5, 125, 8)→5 × 8 × 3 = 120
≠ 125
Second option:
(15, 405, 9)→15 × 9 × 3 = 405
Third option:
(15, 305, 7)→15 × 7 × 3 = 315
≠ 305
Fourth option:
(11, 265, 8)→11 × 8 × 3 = 264
≠ 265
So, only the second option follows the same pattern as followed by the given set of numbers. Hence, the second option is correct.
