Correct Answer - Option 1 : 8 litre
Given:
The initial ratio of A and B is 1 : 4
Amount of B becomes 44 litres
Concept used:
When some fraction of mixture is taken out then the ratio of the remaining mixture is the same
Calculation:
Let the initial ratio of the mixture be x and 4x respectively
And, 25% of the mixture is taken out then the quantity of mixture becomes 3x/4 and 3x
Now, According to the question:
3x + 20 = 44
⇒ 3x = 24
⇒ x = 8
∴ The initial Amount of A is 8 litre
