Direction: The line graph shows the distance covered by different trains in km and the data in the table shows the time taken by different trains to cover the distance (in hours). Time taken by different trains in hours
Train | Time |
\[{{T}_{1}}\] | 30 hours |
\[{{T}_{2}}\] | 9 hours 40 minutes |
\[{{T}_{3}}\] | 17 hours 30 minutes |
\[{{T}_{4}}\] | - |
\[{{T}_{5}}\] | 21 hours 36 minutes |
\[{{T}_{6}}\] | - |
\[{{T}_{7}}\] | - |
A) 7 : 6
B) 6 : 7
C) 9 : 8
D) 7 : 8
E) 11 : 9
Correct Answer: D
Solution :
Distance covered by train \[{{T}_{4}}\] and \[{{T}_{7}}\] are 900 km and 1200 km respectively. Let the speed of trains \[{{T}_{4}}\] and \[{{T}_{4}}\] be 6x and 7x respectively. Then the ratio of time taken by \[{{T}_{4}}\] to that by T, \[=\frac{900}{6x}:\frac{1200}{7x}=63:72=7:8\]You need to login to perform this action.
