The ratio of the radii of two taps \[{{T}_{1}}\]and \[{{T}_{2}}\] is 2:1. Water is flowing through them with the same speed. What is the ratio of the time required to completely fill two identical drums kept under \[{{T}_{1}}\] and \[{{T}_{2}}\]
A)2:1
B)1:2
C)4:1
D)1:4
Correct Answer:
D
Solution :
[d] Area ratio of the taps \[=4:1\] Time taken to fill \[=\frac{1}{4}:1=1:4\]
