Question

Salman had $\frac{1}{4}$ L of kerosene left in a bottle. He needs to sell 800 mL of kerosene to his customer. How much more kerosene should he pour into the bottle before handing it to the customer?

• A.
  450 mL
• B.
  550 mL
• C.
  650 mL
• D.
  400 mL

Answer 1

The correct option is B

550 mL
We know that 1 L = 1000 mL,
Volume of kerosene in the bottle = $\frac{1}{4}$ L
= $\frac{1}{4}\times$ 1000 = 1000 $÷$ 4 = 250 mL

Total kerosene to be sold to the customer = 800 mL
Volume of kerosene to be added
= 800 mL - 250 mL = 550 mL
