Question

How much water is stored in the beaker shown in the figure?

• A. $40ml$
• B. $50ml$
• C. $45ml$
• D. $42ml$

Answer 1

The correct option is B $50ml$

From the figure, it can be noticed that the water is filled between $40ml$ and $60ml$. Counting each sub division on scale, there are 4 sub divisions between every marked value in the problem figure.
This means value of each subdivision is
$\frac{60-40}{4}=5ml.$
Water is filled $2$ subdivisions above $40ml.$
Which means the water level is $40+(2\times 5)=50ml.$
