In A mixture of 180 liters. the ratio of milk and water is 5 : 1. If this ratio is to be 3 : 2, then find the quantity of water to be further added.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 70 litres.
The total quantity of mixture = 180 liter
The ratio of milk and water = 5 : 1...............(1)
After water add the new ratio of milk and water = 3 : 2...................(2)
milk is the same in both conditions,
So, multiplying by 3 in (1) and 5 in (2)
Old Milk : Water = 15 : 3
New Milk : Water = 15 : 10
So, added water = (10 - 3 = 7 unit)
15 + 3 = 180 (given)
⇒ 18 = 180
⇒ 1 = 10
So, 7 = 70 liter
So, 70 liters water is added to the new mixture
