Question 1196732
.
What is the largest possible value of 'm' in 653m2 such that it is divisible by 3?
~~~~~~~~~~~~~~~~~~~~~



The key idea is that the sum of the digits must be divisible by 3.


Using this idea, can you do the rest on your own ?

<U>Comment from student</U> : Hello Madam, Yes, I have tried this: 6+5+3+M+2=16+M So M can be 2,5,8... that can be divisible by 3. 
but how can I choose 2,5 or 8? which one?



<U>My response</U> : &nbsp;&nbsp;Hello, you made great progress, &nbsp;and I am glad to see it &nbsp;(&nbsp;!&nbsp;)


Now strain your mind a bit more and choose  &nbsp;&nbsp;M = 8 - - - it will provide you the maximum possible value.


Isn't it obvious ?
