Joe is the captain of a large boat. We write ‘A’ for his age, ‘C’ for the number of his children, and ‘L’ for the length of his boat. We are given that :
(i) A. C. L = 32118;
(ii) ‘L’ has an integral value;
(iii) ‘C’ counts both a non-zero number of sons and a non-zero number of daughters, the number of sons and daughter are not the same.
(iv) 100>A>C

What is the value of ‘A’?

W, X, Y and Z are 4 positive real numbers. Three numbers can be chosen from them and their sum is found out. This is done for all such sets. The product of the four given real numbers is 5. What is the minimum value of the product of the sums of the sets?
