It water is mixed with milk to gain \(20\%\) by selling the mixture at cost price. Then ratio of water to milk in mixture, is :
- A \(4: 5\)
- B \(2: 5\)
- C \(1: 5\)
- D \(5: 2\)
Answer & Solution
Correct Answer
(C) \(1: 5\)
Step-by-step Solution
Detailed explanation
Gain \(\% = \frac{\text{Water}}{\text{Milk}} \times 100\) \(20 = \frac{W}{M} \times 100\) \(\frac{W}{M} = \frac{20}{100} = \frac{1}{5}\) Ratio of water to milk is \(1:5\)
