Question

Which greatest digit number should replace m so that the number 77m09 is divisible by 3

Answer 1

Answer:

4

Step-by-step explanation:

First do addition of the given number i:e 7+7+0+9=23

Therefore if we replace m by 4 the total sum would be 27 and the divisional property of 3 states that the total sum of number should be divisible by 3.

now we need greatest digit number ie greatest one digit number so add 3more in 27 that is 30 and the number is 7

30-23=7
