The price of a jewel, passing through three hands, rises on the whole by 65%. If the first and the second sellers earned 20% and 25% profit respectively, the profit earned by the third seller is
-
- 20%
- 15%
- 10%
- 5%
Correct Option: C
Let the C.P. of the jewel be $ 100
S.P. for the first person = $ 120
| S.P. for the second person = $ 120 × | = $ 150 | 100 |
Now, let the profit earned by the third person be y%
∴ 150 of ( 100 + y )% = 165
| ∴ 150 × | = 165 | 100 |
| ⇒ 100 + y = | = 110 | 15 |
⇒ y = 110 – 100 = 10%
