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 10 cm and 4 cm 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.
