• Solution:- According to the question ,the format is like ,
A+B=(A+B)+3 [if one is even number in between A & B ]
A+B=(A+B)+4 [ if there are no even number in between A & B]
according to the format
2+7=9+3= 12 (as 7 is even number in between 2 &7)

Answer:
answer is 20
2+7=12 2+7=9
9+7=16
16-2*2=16-4=12
3+12=18. 3+12=15
15+12=27
27-3*3=27-9=18
4+20=28. 4+20=24
24+20=44
44-4*4=44-16=28
so 6+25=? 6+25=31
31+25=56
56-6*6=56-36=20
so answer is 6+25=20
