Question

which of the following is divisible by 3
121,123,124,122.​

Answer 1

Answer:

123.......... because the sum of all digits of the number is divisible by 3

Answer 2

We can check if the number is divisible by 3 by adding up the digits of number and check if the number I visible by 3 ....

I will tell u with example...

Now we have to check for 121 , 123 , 124 and 122.

Now ....

121 = 1+2+1 = 4 and 4 is not divisible by 3 thus 121 isn't divisible by 3 ...now let's check for others...

122= 1+2+2 = 5 ....122 not divisible by 3 ...

123= 1+2+3 = 6 ....6 is divisible by 3 thus 123 is divisible by 3 ...

124= 1+2+4 = 7 ...124 is not divisible by 124....

HOPE THIS HELPS ☺️☺️
