    Hello Harish

    Interesting question.

     

    Since sum of odd numbers is an odd number, 

    _ + _ + _ = 30

    Sum of 3 odd numbers can never be even.

    So, the answer is no solution.

     

    We could also apply some tricks.

     

    Solution 1

    Using Factorial

    11 + 3! + 13 = 30

    11 + (3 * 2 * 1) + 13 = 30

    11 + 6 + 13 = 30

    30 = 30

     

    Solution 2

    We could also use decimals

    11.3 + 15.7 + 3 = 30
