Explanation:
- Let the printed price be \( P \).
- The shopkeeper offers a 10% discount, selling goods at 90% of the printed price: \( 0.9P \).
- He gains 20% on the cost price \( C \). Therefore, the selling price \( = C + 0.2C = 1.2C \).
- Equating the selling price expressions: \( 0.9P = 1.2C \).
- Rearrange to find the ratio \( C : P = 0.9 : 1.2 \).
- Simplify the ratio: \( C : P = 3 : 4 \).
?? 3 : 4 is the correct ratio. .
