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 /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)

(35, 12, 29)

(23, 16, 31)

• A. (21, 25, 29)
• B. (33, 30, 27)
• C. (18, 12, 21)
• D. (19, 8, 23)

Answer 1

Answer:

D. (19, 8, 23)

To find the logic behind the given sets, let's analyze the relationship between the three numbers $(first, second, third)$ in each set:

Set 1: (35, 12, 29)

• Find the absolute difference between the first and the third number:
  $\vert{}35 - 29\vert{} = 6$

• Multiply this difference by $2$ to get the second number:
  $6 \times 2 = 12$

---

Set 2: (23, 16, 31)

• Find the absolute difference between the first and the third number:
  $\vert{}23 - 31\vert{} = 8$

• Multiply this difference by $2$ to get the second number:
  $8 \times 2 = 16$

---

Logic Formula:

$\text{Second Number} = \vert{}\text{First Number} - \text{Third Number}\vert{} \times 2$
(19,8,23)

$23-19=4$

$4\times2=8$
