• A. $40litres$
• B. $16litres$
• C. $60litres$
• D. $80litres$

Answer 1

The correct option is B $16litres$

Let the quantity of milk be $x$ liter.

lost of 1-liter milk is $3Rs=300$ paise

Then, we have

$(x+16)\times$ $150$ $=x\times 300+16\times 0$ (cost of water)

$\Rightarrow 150x+2400=300x$

$2400=150x$

$x=16$

Thus, the quantity of milk in the

the mixture is $16liter.$
