Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given set.
(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.)
(54, 32, 66)
(49, 31, 54)
Option 1: (39, 18, 63)
Option 2: (44, 28, 52)
Option 3: (68, 49, 55)
Option 4: (55, 30, 70)
Correct Answer: (39, 18, 63)
Solution :
Given:
(54, 32, 66); (49, 31, 54)
In the given sets, subtract the second number from the first and multiply the resultant with 3 to obtain the third number.
(54, 32, 66)→54 – 32 = 22; 22 × 3 = 66
(49, 31, 54)→49 – 31 = 18; 18 × 3 = 54
Let's check the options –
First option:
(39, 18, 63)→39 – 18 = 21; 21 × 3 = 63
Second option:
(44, 28, 52)→44 – 28 = 16; 16 × 3 = 48
≠ 52
Third option:
(68, 49, 55)→68 – 49 = 19; 19 × 3 = 57
≠ 55
Fourth option:
(55, 30, 70)→55 – 30 = 25; 25 × 3 = 75
≠ 70
So, only the first option follows the same pattern as followed by the given set of numbers. Hence, the first option is correct.
