Answer 1

Answer:

please mark as brainiest answer

Step-by-step explanation:

Let the original price of the jewel be Rs. P and the profit earned by the third seller be x%

S.P. of 1st seller = Rs.  120/100× P = C.P. of 2nd seller

S.P of 2nd seller =Rs.  125/100×  120P

/100 = C.P. of 3rd seller

∴S.P. of 3rd seller =Rs.  (100+x)/100×  125

/100  × 120P/100

Given,

Rs.  (100+x)/100×  125

/100  × 120P/100=  165P

(100+x)=2/3×165=110⇒x=110−100=10%
