Answer 2

Answer:

a first take even no that is 9+5=14

then take odd that is 1+6+7=14

now subtract it =14-14=0

so this is divisible by 11

b same here even no 3+4+5=12

odd=2+7=9

now subtract=12-9=3

this is not divisible by 11

c. same here even 2+5+1+3=11

odd 3+9+7+8+6=33

now subtract =33-11=22

this is divisible by 11

d.same here even 7+8=15

odd 9+6=15

now subtract =0

Step-by-step explanation:

to check divisibility take the sum of odd no and even no and then subtract them

if the answer is 0 or the answer is divisible by 11 then the no is also divisible
