Explanatory Answer

Method of solving this CAT DILR Question from Data Sufficiency question

Since (a + b) and (a  b) are not uniquely determined we can’t find a & b nor we can uniquely determine (a+ b), so we cant even apply formula. Hence cannot be determined even with the help of both statements.
