A container contains 48 litres of buffalo milk. From this container 8 litres of buffalo milk was taken out and replaced with cow milk. This process was repeated further 3 more times. How much buffalo milk is there in the container now ?
- A 22 litres
- B 23.14 litres
- C 24 litres
- D 24.5 litres
Answer & Solution
Correct Answer
(B) 23.14 litres
Step-by-step Solution
Detailed explanation
\( \text{Remaining quantity} = \text{Initial quantity} \times \left(1 - \frac{\text{Amount taken out}}{\text{Total volume}}\right)^n \) \( = 48 \times \left(1 - \frac{8}{48}\right)^4 \) \( = 48 \times \left(1 - \frac{1}{6}\right)^4 \) \( = 48 \times \left(\frac{5}{6}\right)^4 \)…
