According to the logic used in the first pair, replace the question mark with the appropriate option given to

54023 ∶ 563 ∶∶ 37125 ∶ ??  

Logic : Sum of the digits of 1st number = Sum of the digits of 2nd number

So,

• 54023 ∶ 563

5 + 4 + 0 + 2 + 3 = 5 + 6 + 3

14 = 14 (LHS = RHS)

Similarly,

• 37125 ∶ ??

3 + 7 + 1 + 2 + 5 = 18

Thus, as per the logic given checking the options :

• Option - (1) : 674

​6 + 7 + 4 = 17

Incorrect, as sum of the digits required is 18.

• Option - (2) : 676​

​6 + 7 + 6 = 19

Incorrect, as sum of the digits required is 18.

• Option - (3) : 675

​6 + 7 + 5 = 18

Correct, as sum of the digits required is 18.

• Option - (4) : 673​

​6 + 7 + 3 = 16

Incorrect, as sum of the digits required is 18.

Hence, "Option - (3)" is the correct answer.
