given that all numbers are different odd numbers
STE 1 : sum of numbers is equal to 16 : when considering different odd number, only 1,3,5,7 sum up to 16. Median 4 : sufficient
STE 2 : product of 3 numbers equal to 15. Factorize 15 to its prime factors to get 1,3,5. since it has been given that all numbers are different odd numbers next number should be greater than 5 : sufficient

Hope this helps

I got this correct but have a doubt in interpreting statement (2).

The product of the 3 numbers of a, b, c, and d is 15

The product of the 3 numbers of a, b, c, i.e. a * b * c = lets say x AND D is 15.

How can product of x * D be 15 if all are different positive odd numbers.

This has to do with the wording in the question, i think the question means that 3 numbers in the set (a, b, c, d) multiply together give 15 instead of a x b x c x d = 15.

I guess there's a wording problem

The second statement is not clear. Maybe, it means that a * b * c = d = 15? It is true for a = 1, b = 3, c = 5 and d = 15
