Question

In 39*43, replace * by the smallest number to make it divisible by 11 ?​

Answer 1

Answer:

Dear Friend,

First let's get our facts clear. A number is only divisible by 11 when adding up all the alternate numbers and subtracting them would give you 0 or a multiple of 11.

Eg. 1331

1+3=4

3+1=4

4-4=0

So 1331 is divisible by 11.

Now let's go on to figure the answer of your question.

39_43

Let the blank number be x.

3+x+3=6+x

9+4=13

So we know that 13=6+x

which is 7=x

So the least number to fill the gap is 7

RECHECK

3+7+3=13

9+4=13

13-13=0

So the answer is correct.

Hope it helped

Have a nice day

Let the no be x

(3+3+x)-(9+4)=0

x-7=0

x=7
