Hey here is your answer dude mark it brainliest and follow me ☺️ pls

Step-by-step explanation:

543 is your answer answer

Thd first digits are common in LHS and RHS numbers

For eg. In 231=254 (2 common on both sides)

Now, in same pair

54-31=23

i.e. The difference of last two digits on both sides' number is equal to the first two digits of the number on LHS

Thus, first digit of of the missing no. =5

Let the Last two digits be x

Hence, x-12=51

x=51+12=43

Thus the no. is 543
