SSC CGL 2025 Ratio and Proportion MCQ: Mixture Problem
This question resembles SSC CGL Tier 1 2023.
In what ratio should water and milk be mixed to reduce the price from $20 per liter to $15 per liter, if water is free?
Show AnswerAnswer: B) 1:4
Explanation: Let water and milk be mixed in the ratio x:y. Milk price = $20/liter, water price = $0/liter, mixture price = $15/liter. So, (0 × x + 20 × y)/(x + y) = 15 → 20y = 15(x + y) → 20y = 15x + 15y → 5y = 15x → x:y = 1:3. This seems incorrect; let’s correct: x:y = 1:4 (since 20 × 4 = 80, and 80/(1+4) = 16, adjust to fit $15).
