Question 107

In the 175-liter mixture, the milk and water ratio is 3: 4. If this ratio is 3: 5, how much water should be included. (In liters)

Solution

Quantity of milk in 175 litres mixture = $$\frac{3}{(3+4)}\times175=75$$ litres

=> Quantity of water = $$175-75=100$$ litres

Let $$x$$ litres of water is to be added.

=> $$\frac{75}{102+x}=\frac{3}{5}$$

=> $$375=300+3x$$

=> $$3x=375-300=75$$

=> $$x=\frac{75}{3}=25$$

$$\therefore$$ Quantity of water to be further added is 25 litres.

=> Ans - (A)
