Question

Which of the following jar is $\frac{3}{4}$th empty?

• A.
• B.
• C.

Answer 1

The correct option is B

Capacity of jar = 1 L = 1000 mL
¼ of capacity = ¼ of 1000 mL= 250 mL
¾ of capacity = 3× ¼ of capacity = 3 × 250 mL = 750 mL

If we empty ¾ of the jar, It will have 1000mL - 750mL = 250 mL of water.
In option A, 250mL water is filled. It is the correct answer.
In option B, 500 mL is filled. It is the wrong option.
In option C , 750 mL is filled. It is the wrong option
