• A. $40$ liters
• B. $50$ liters
• C. $60$ liters
• D. $80$ liters

Answer 1

Answer: (D)

$80$ liters

Let there be $x$ liters of milk

$(x+16)90=x\times 108$

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

$108x-90x=90\times 16$

$18x=90\times 16$

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

$x=5\times 16=80$

$80$ liters of milk is there in the mixture.
