\[\begin{array}{*{20}{c}} {}&{ + 16\% }&{ - 12\% } \\ {}&{\text{I}}&{{\text{II}}} \\ {{\text{Cost Price}}}&{{{25}_{ \times 22}}}&{{{25}_{ \times 29}}} \\ {{\text{Profit/Loss}}}&{{4_{ \times 22}}}&{ - {3_{ \times 29}}} \\ {{\text{Sale Price}}}&{{{29}_{ \times 22}}}&{{{22}_{ \times 29}}} \end{array}\]
Cost Price = 25(29 + 22) = 25 × 51
