Q. 245.0( 1 Vote )
Fill in the blanks to make the statements true.
If 
then A = ……………… and B = …………… .
Answer :
Adding all the digits according to their places,
20 + B + 10A + B = 80 + A
9A + 2B = 60
9A = 60-2B
Since A and B both are whole numbers, 60-2B should be divisible by 9.
60-2B = 54 so B = 3.
Substituting B = 3 in 9A + 2B = 60,
we get A = 6.
