Question

A juice seller fills glasses from a big cylindrical container of height 35.2cm and radius 10cm. He charges Rs10 for each glass of height 10cm and 4cm radius. 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 $=\frac{volumeofthevessel}{volumeofeachglass}$

$=\frac{\pi \times 10\times 10\times 35.2}{\pi \times 4\times 4\times 10}$

$=22$

Therefore, amount received by the shop keeper = Rs.10 × 22 = Rs.220.
