A*(4+(B/100)) = 108.81
4A + AB / 100 = 10881/100
4A + (AB/100) = 108 + (81/100)
So,
4A = 108 and AB/100 = 81/100 => AB = 81
Hence
A=108/4=27 and by solving AB 81, B = 3
Thus A+B = 30

Step1: A(400+B)=10881
Step2: 10881= 9*3*403 (Find factors for 10881, Divide by 9, and then divide by 3)
Step3: A(400+B) = 9*3*403
Step4: A(400+B) = 27*403
Step5: A(400+B) = 27(400+3)
So A=27 and B=3.
57 is the correct answer, where value of A is 27 and B is 30.
818 if both a and b are integers
