Question

A juice seller fills juice into cylindrical glasses from a big cylindrical container of height 35.2 cm and radius 10 cm. He charges ₹10/- for a glass of height 10 cm and radius 4 cm. The amount he earns by selling the juice is Rs ____.
$(Use\pi =\frac{22}{7})$

• A. 220

Answer 1

The correct option is A 220

We know that,
volume of a cylinder $=\pi r^{2}h$

Number of glasses of juice that are sold
$=\frac{\text{volume of the vessel}}{\text{volume of each glass}}=\frac{\pi \times 10\times 10\times 35.2}{\pi \times 4\times 4\times 10}=22$

$\therefore$ The amount earned by the shopkeeper
$=\text{Rate of each glass}\times \text{Total number of glasses}$
$=10\times 22=₹220/-$
