Question

A milk packet conatins 10% of water. What will be the quantity of milk if there is 250ml of water?

• A. 2500 L
• B. 2500 mL
• C. 250 mL
• D. 25000 mL

Answer 1

The correct option is B 2500 mL

$\text{Let the quantity of milk be}\text{x}mL$

According to question,
A milk contains 10% of water. And x mL of milk contains 250 mL of water

$\text{So,}10\%\text{of x}=250$
$\frac{10}{100}\times \text{x}=250(\because 10\%=\frac{10}{100})$

$\frac{\text{x}}{10}=250$

$\text{x}=250\times 10$

$\text{x}=2500mL$

Hence, the quantity of milk required is 2500 mL.
