Given :
- Selling price is Rs 208 .
- Profit percentage is 4% .
To Find :
Solution :
Let us suppose ,
→ CP = Rs x
Therefore the profit will be ,
→ Profit = SP - CP
→ Profit = 208 - x
Now we know that ,
→ Profit% = profit/CP * 100
Substituting the respective values ,
→ 4 = (208-x)/x * 100
→ 4 * x = (208- x)*100
→ 4x = 20800 - 100x
→ 100x + 4x = 20800
→ 104x = 20800
→ x = 20800/104
→ x = 200
Hence the cost price is Rs 200.
I hope this helps.
