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, 91, 98); (4, 52, 56)
Option 1: (12, 156, 168)
Option 2: (3, 36, 42)
Option 3: (8, 80, 96)
Option 4: (5, 25, 60)
Correct Answer: (12, 156, 168)
Solution : Given:
(7, 91, 98); (4, 52, 56)
Like, (7, 91, 98)→7 × 13 = 91; 7 × 14 = 98
(4, 52, 56)→4 × 13 = 52; 4 × 14 = 56
Let's check the options –
First option: (12, 156, 168)→12 × 13 = 156; 12 × 14 = 168
Second option: (3, 36, 42)→3 × 13 = 39 ≠ 36; 3 × 14 = 42
Third option: (8, 80, 96)→8 × 13 = 104 ≠ 80; 8 × 14 = 112 ≠ 96
Fourth option: (5, 25, 60)→5 × 13 = 65 ≠ 25; 5 × 14 = 70 ≠ 60
So, only the first option follows the same pattern as followed by the given set of numbers. Hence, the first option is correct.
