Question

A juice seller fills glasses from a big cylindrical container of height $35.2cm$ and radius $10cm$. He charges Rs. $10$ for each glass of height $10cm$ and radius $4cm$. The amount of money he earns by selling juice is [Take $\pi =\frac{22}{7}$]

• A. Rs.220
• B. Rs.110
• C. Rs.170
• D. Rs.190

Answer 1

The correct option is A

Rs.220

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, amount received by the shop keeper $=$ Rs.$10\times 22=$ Rs. $220$
