Ram and Shyam start walking in opposite directions. Ram covers 6 km and Shyam 8 km. Then, Ram turns right and walks 8 km and Shyam turns left and walks 6 km. How far everyone is from their starting point ?

Options

A. 11 km
B. 8 km
C. 9 km
D. 10 km

Answer

D

Explanation

From above figure we can see that both are standing equal distance from starting point
`:.` Required distance `=sqrt((8)+(6))" "` (by Pythagoras theorem)
`=sqrt(64+3C)`
`=sqrt(100)=10" km"`
Hence everyone is 10 km far from their starting point.
