Question : Directions: Select the option 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, 1, 3)
(12, 2, 5)
Option 1: (30, 8, 11)
Option 2: (26, 4, 20)
Option 3: (32, 6, 18)
Option 4: (40, 10, 30)
Correct Answer: (30, 8, 11)
Solution :
Given:
(7, 1, 3) (12, 2, 5)
In the above-given set of numbers, multiply the third number by 2 and then subtract the result from the first number to get the second number.
(7, 1, 3)→3 × 2 = 6; 7 – 6 = 1
(12, 2, 5)→5 × 2 = 10; 12 – 10 = 2
Let's check each option –
First option:
(30, 8, 11)→11 × 2 = 22; 30 – 22 = 8
Second option:
(26, 4, 20)→20 × 2 = 40; 26 – 40 = –14 ≠ 4
Third option:
(32, 6, 18)→18 × 2 = 36; 32 – 36 = –4 ≠ 6
Fourth option:
(40, 10, 30)→30 × 2 = 60; 40 – 60 = –20 ≠ 10
So, (30, 8, 11) follows the same pattern. Hence, the first option is correct.
