33. Write all the numbers of this form.​

Answer 1

Answer:

aabaaa is your ans its divisiable by 898

Answer 2

Answer:

21285

Step-by-step explanation:

A+B+A+A= 0,3,6,9…

For divisibility by 11, Sum of odd Place digits= A+B+A=2A+B

Sum of even place digits=2A

Difference= B =0,11,222

Since B is a single digit B must be Zero

The numbers are 33033,66066,99099

3. 212x5 is a multiple of 3 and 11

2+1+2+x+5=multiple of 3 i.e 3,6,9….

So x=2,5,8…

But it should also divisible by 11

Sum of Odd place digits= 2+2+5 =9

Sum of even place digits=x+1

Difference =9- (x+1) should be 0,11,22..

So x=8
