1. A jar contains a mixture of oil and water in the ratio 22 :3 . 50 litres of the mixture was taken out and 25 litres of water was added to it. If water was 34% in the resultant mixture, what was the initial quantity of the mixture (in litres ) in the jar?
- A. 175
- B. 175
- C. 175
- D. 175
Answer: Option D
Explanation:
Let, Oil = 22X & Water = 3X
After removing 22 litre
Oil removed = (22x50)/25 = 44; Here, [22+3 = 25] [removed= 50] [Oil ratio= 22]
Water Removed = (3x50)/25 = 6;Here, [22+3 = 25] [removed= 50] [Water ratio= 3]
Now as per the Question,
>22X-44 : 3X-6+25 = 66:34 [ 34% water So Oil 66% SO ratio 66:34 ]
>374X-748 = 99X+627
>X= 5
So Initial Quantity= 22x5+3x5 = 125 litre. Ans.
