Gopi goes from place A to B to buy an article costing 15% less at B, although he spends Rs. 150 on travelling, still he gains Rs. 150 compared to buying it at A. His profit percent is :
-
- 4.5
- 6
- 7.5
- 8
Correct Option: C
Let Cost price of article at place A = Rs. y
At 15% less ,
| ∴ Price at place B = Rs. | = Rs. | 100 | 20 |
According to the question,
| y - |  | 17y | + 150 |  | = 150 | |
| 20 |
| ⇒ y - | = 300 | 20 |
| ⇒ | = 300 | 20 |
| ⇒ | = 300 | 20 |
| ⇒ y = | = Rs. 2000 | 3 |
| ∴ Price at place B = | × 2000 = Rs. 1700 | 20 |
Actual price = Rs. (1700 + 150) = Rs. 1850
Profit = Rs. (2000 – 1850) = Rs. 150
| ∴ Profit percent = Rs. | | × 100 | | = 7.5% | |
| 2000 |
