In two containers A and B, milk and water are in the ratios 5 : 3 and 11 : 5 respectively. The two mixtures are mixed in the ratio 1 : 1 by volume. Find the ratio of milk to water in the new mixture.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 21 : 11
Equal volumes are taken, so a volume that both ratio totals (8 and 16) divide into makes the counting easy: take 16 litres from each container.
From A: milk \(\displaystyle =\frac{5}{8}\times16=10\), water \(=6\)
From B: milk \(=11\), water \(=5\)
Total: milk \(=10+11=21\), water \(=6+5=11\)
The new mixture has milk and water in the ratio 21 : 11.
