Question

Replace the * with the smallest digit to make it divisible by 11

45*53
PLEASE ANSWER !!!!

Answer 1

Answer:

Step-by-step explanation:

let us assume the no. to be as 45a53,

for it to be divisible by 11,

(4+a+3)-(5+5) = 11n (as divisibility rule for 11 is : difference between even places and odd places should be a multiple of 11)

7+a-10 =11n

a= 11n+3

for n=0 ,a=3

for n=1 ,a=14

for n=2,a=25

and for any value other than n=0 value of a does not lie in between 0 to 9 (since a is a digit it should in between 0 to 9)

So, so only possible value of a is 3

so the required no. is 45353
