A man sold an article at a loss of 20%. If he had sold it for $ 50 more, he would have gained 5%. The cost price of the article was
-
- $ 250
- $ 300
- $ 180
- $ 200
Correct Option: D
Let the CP of the article be $ y
| SP of the article at 20% loss = y × | = | 100 | 5 |
In second case,
| + 50 = | 5 | 100 |
| ⇒ | + 50 = | 5 | 20 |
| ⇒ | - | = 50 | 20 | 5 |
| ⇒ | = 50 | 20 |
| ⇒ | = 50 | 20 |
⇒ y = $ 200
We can find required answer with the help of given formula :
Here, a = 20%, R = $ 50, b = 5%
| C.P. = | b + a |
| C.P. = | 20 + 5 |
| C.P. = | = $ 200 | 25 |
