Question
Select the set in which the numbers are related in the
same way as are the numbers of the following sets. (Note: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g., 13 – Operations on 13 such as adding/deleting/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.) (12, 15, 18) (45, 35, 25)Solution
ATQ, In the first set (12,15,18), the difference between the numbers is +3. In the second set (45,35,25), the difference is -10. Now, we check the options: (15,20,25), the difference is +5 (constant), which fits the pattern of having a consistent difference between numbers. So, the correct answer is (15,20,25).
