Solution

The correct option is A

₹ 220


Given:
Radius of cylindrical container, rc = 10 cm
Height of cylindrical container, hc = 35.2 cm
Radius of cylindrical glass, rg = 4 cm
Height of cylindrical glass, hg = 10 cm

Volume of the cylindrical container =πrc2hc=π×102×35.2

Volume of the glass =πrg2hg=π×42×10

Number of glasses of juice that are sold =volume of the cylindrical containervolume of each glass

=π×10×10×35.2π×4×4×10

=22

The amount received by the juice seller = cost of each glass × number of glasses sold
= 10×22= 220

[Alternatively,
Volume of the cylindrical container =πrc2hc=π×102×35.2
Volume of the glass =πrg2hg=π×42×10
Given that the seller charges ₹ 10 for a glass of height 10 cm and and radius 4 cm.
i.e., the seller charges ₹ 10 for a volume of π×42×10
Hence, the amount to be charged for a volume of π×102×35.2 is,
(π×102×35.2)×10π×42×10
= 220]
