Question

a man sold two watches at rs. 240 each on one he gained 7% and on the other he lost 7%. find the gain or loss in the transaction​

Answer 1

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
