28 4 % 7
Correct Option: B
Let the S.P. of 60 articles be y.
| ∴ S.P. of 15 articles = | 4 |
| C.P. of 60 articles = y - | = | 4 | 4 |
| Gain = y - | = | 4 | 4 |
| ∴ Gain % = | × 100 | ( 3y / 4 ) |
| Gain % = | × | × 100 | 4 | 3y |
| Gain% = | = 33 | % | 3 | 3 |
We can find required answer with the help of given formula :
Here, p = 60, q = 15
| Gain% = | p - q |
| Gain% = | 60 - 15 |
| Gain% = | 45 |
| Gain% = | = 33 | % | 3 | 3 |
