33 1 % 3 -
31 1 % 4
Correct Option: A
According to question ,
SP of 12 ball pens = CP of 12 ball pens + SP of 4 ball pens.
⇒ SP of 8 ball pens = CP of 12 ball pens
| ∴ Gain percent = | × 100 = 50% | 8 |
We can find required answer with the help of given formula :
Here, p = 12, q = 4
| Profit% = | p - q |
| Profit% = | = 50% | 12 - 4 |
