Question

If the cp of 13chocolates is equal to the SP of 14 chocolates find the profit or loss percent

Answer 1

Let, the CP of each chocolate be, 'X'

CP of 13 chocolates = 13 × X

                                  = 13X

The CP of 14 chocolates = 14 × X

                                          = 14X

By condition, the SP of 14 chocolates = 13X

∴ SP∠ CP ( 13X ∠ 14X ) so, there is a loss

∴ Loss = ( 14X - 13X )

           = X

∴ Loss % = X/14X × 100

                 = 7 +1/7% ( 7 whole of 1/7 %)
