How did answer came please explain​

Answer 1

Answer:

When you don't know how to solve this simple problems

Then substitute values from 0-9 (which is only possible values) in which you will may get a single or multiple results.

Step-by-step explanation:

However let's solve now

You notice that all the the unit digits are same

And in order to get same unit digit the possible values are 1,5 and 6

because 1*1=1 2*2=2 3*3=9 4*4=6 5*5=5 6*6=6 7*7=9 8*8=4 9*9=1 0*0=0

Only unit digits are taken into consideration

So possible values are 1,5 and 6

substitute these values in place of A

11*1=11 which is not the answer because the tens digit is not 9

15*5=75 which is not the answer because the tens digit is not 9.

16*6=96 which is the answer because the tens digit is 9 and this is only the possible value of A being 6 because this result only gives the tennis digit as 9.
