Question

Which greatest digit should replace m so that the number 10m6415 is divisible by 11?
Please explain l am really confused l saw a different answer but l didn't get it...

Answer 1

Answer:

to find the value of M, we have to apply the divisibility test for 10m6415

1+m+4+5 - 0+6+1

10 - 7

3

the rule of divisibility test for 11 is the subtracted number should be 11 or a multiple of 11

so,

3 + 8 = 11

Answer 2

Answer:

8

Step-by-step explanation:

The divisibility rule of 11 is to add alternative digits and subtract it so it will become

Number: 10m6415 =

1 + m + 4+ 5 = 10

0+ 6 + 1 = 7 =then we have to subtract it from sum 1 - sum 2 because in divisibility rule of 11  we get two sets of numbers to add when we grouped it alternatively so 10 - 7 =

3 + m =11 - Because m cannot be greater than 11

m = 8

let's check the answer by placing 8 in the number - 1086415

so grp 1 = 1+8+4+5= 18

grp 2 = 0+6+1=7

so 18 -7 = 11

and the difference is 11 and 11 is divisible by 11 so the number is divisible .

Ans: 8
