Divisibility Rule of 9:if the sum of digits of the number is divisible by 9 , then the number is divisible by 9 .Divisibility Rule of 4:If the last two digits of a number are divisible by 4 , the number is divisible by 4 .Calculation:$36=9 \times 4$If any number is divisible by 9 and 4 , then the number itself is divisible by 36 also.We need to check it by option.Option 1:Number $=47502$To check the divisibility with 9 .The sum of digits $=4+7+5+0+2=18$18 is divisible by 9 . So the number is also divisible by 9 .To check the divisibility with 4.The last two digits $=02$02 is not divisible by 4 . So the number is not divisible by 4 .47502 is not divisible by 36 .Option 2:Number $=29412$To check the divisibility with 9 .The sum of digits $=2+9+4+1+2=18$18 is divisible by 9 . So the number is also divisible by 9 .To check the divisibility with 4.The last two digits $=12$12 is divisible by 4 . So the number is divisible by 4 .29412 is divisible by 36 .
