Question

A mixture of a certain quantity of milk with 16 litres of water is sold at 90 paise per litre. of pure milk be worth rs 1.08 per litre. how much milk is there in the mixture

Answer 1

let the quality of milk be = x litre
cost of 1 litre milk is = rupees 1.08
=108paise
(x+16) ×90=x×108+16×0( cost of water is 0)
90x+16×90=108x
18x=16×90/18=80
quantity of milk=80litres

Answer 2

Answer:

80 Liters

Explanation:

Let the quantity of milk be $x$ litre. cost of 1 litre $\mathrm{milk}=\mathrm{Rs} .1 .08=108 \mathrm{P}$

Then, we have $(x+16) \times 90=x \times 108+16 \times 0(\cos t \text { of water is } 0)$

$\Rightarrow 90 x+16 \times 90=108 x$

$\Rightarrow 18 x=16 \times 90$

$\Rightarrow x=\frac{16 \times 90}{18}=80$

Thus, the quantity of milk is $80 \mathrm{L}$
