Answer» (i) 134 We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4. Here, number formed by last two digits is 34, which is not divisible by 4. Hence, 134 is not divisible by 4. (ii) 618 We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4. Here, number formed by last two digits is 18, which is not divisible by 4. Hence, 618 is not divisible by 4. (iii) 3928 We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4. Here, number formed by last two digits is 28, which is divisible by 4. Hence, 3928 is divisible by 4. (iv) 50176 We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4. Here, number formed by last two digits is 76, which is divisible by 4. Hence, 50176 is divisible by 4. (v) 39392 We know that if number formed by last two digits of a given number is divisible by 4, then entire given number is divisible by 4. Here, number formed by last two digits is 92, which is divisible by 4. Hence, 39392 is divisible by 4. |
