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.)
(3, 4, 24)
(4, 5, 40)
Option 1: (4, 6, 35)
Option 2: (5, 7, 42)
Option 3: (3, 7, 21)
Option 4: (2, 7, 28)
Correct Answer: (2, 7, 28)
Solution :
Given:
(3, 4, 24); (4, 5, 40)
In the above-given sets, multiply 2 by the product of the first and second numbers.
(3, 4, 24)→3 × 4 = 12; 12 × 2 = 24
(4, 5, 40)→4 × 5 = 20; 20 × 2 = 40
Let's check each option –
First option:
(4, 6, 35)→4 × 6 = 24; 24 × 2 = 48
≠ 35
Second option:
(5, 7, 42)→5 × 7 = 35; 35 × 2 = 70
≠ 42
Third option:
(3, 7, 21)→3 × 7 = 21; 21 × 2 = 42
≠ 21
Fourth option:
(2, 7, 28)→2 × 7 = 14; 14 × 2 = 28
So, (2, 7, 28) follows the same pattern. Hence, the fourth option is correct.
