In a mixture two liquids A and B are in the ratio 5 : 3. When 8 litres of mixture are drawn off and the filled with liquid B, the ratio of A and B becomes 1 : 1. How many liters of liquid A was there initially?
Answer & explanation
Correct answer: option 3
Method one:
The ratio A : B
5 : 3
So, the answer will be in the multiple of (5). Therefore, 25 liters is the answer.
Method two:
A : B
5 : 3
↓+2R = 8 ltrs
5 : 5 (from 1 : 1)
1R = 4
Final Qty. 10R = 10 × 4 = 40 liters = Initial Qty.
Initial ratio = 5 : 3 = 8
8R = 40
1R = 5
Qty. of A initially = 5R = 5 × 5 = 25 liters
