Answer 1

Answer:

I will answer 3rd question

it is divisible by 2

it is divisible by 3

it is divisible by 4

not divisible by 11

Step-by-step explanation:

use divisible rules

for 2:last digit is even nomber

for 3:sum of digits is divisible by 3

for4:last two digits are divisible by 4

for 11:sum of all odd places

sum of all even places

then difference of these two i.e odd and even sum is 0 or 11 table multiple.
