Answer:
Step-by-step explanation:
The cost price of first watch, that he gained 7 %
=> we know the formula
©p = SP × 100/100 + profit.
©p = 240 × 100/100 + 7
©p = 24000/107
©p = 224.30
(ii). The cost price of another watch , that he lost 7%
=> ©p = SP × 100 /100-7
=> ©p = 240 × 100/93
=> ©p = 24000/93
=> ©p = 258.06
then , GAINED.
=> SP - ©p = 240-224.30
=>GAINED = 15.7
=> NOW, LOST
=> SP - ©p = 240-258.06
=> LOSS= 18.6
