**(1) 282****Solution:-**282 is not divisible by 4 but rest are divisible by 4.

Hence, the correct answer is option (1) 282.

**(2) 2213****Solution:-**

Sum of first, second and fourth digit of 1285 = 1 + 2 + 5 = 8, which is equal to third digit of 1285.**Sum of first, second and fourth digit of 2213 = 2 + 2 + 3 = 7, which is not equal to third digit of 2213.**

Sum of first, second and fourth digit of 3074 = 3 + 0 + 4 = 7, which is equal to third digit of 3074.Sum of first, second and fourth digit of 4172 = 4 + 1 + 2 = 7, which is equal to third digit of 4172.

Then, the odd number is 2213.

Hence, the correct answer is option (2) 2213.

**(4) 4223**- (
**1) 11****Explanation:-**

11 is a prime number but are the composite number.Hence, the odd number is 11.

**(1) 5****Explanation:-**5 is a prime number but rest the composite number.Hence, the correct answer is option (1) 5.

**(4) 613****Explanation:-**

613 is not a perfect square of any numbers but rest are the perfect square of 9, 21 and 23.Hence, the correct answer is option (4) 613.

for the third one divisibility by 13,in given options D)4223 is not divisible by 13
