Question

Which smallest digit should replace m so that the
number 778 m 09 is divisible by 3?​

Answer 1

Answer:

DIVISIBILITY FOR 3

If the sum of the numbers is divisible by 4 then the whole number will be divisible by 3.

7+7+8+m+0+9 = 31

31 is not divisible by 3 . 33 is be number which is divisible by 3.

m = 31 + 2

m = 33

so the number (m) is 2.
