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

Abhi says

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.

Guest says

57 is the correct answer, where value of A is 27 and B is 30.

818 if both a and b are integers
