Ram and Shakil run a race of 2000m. First Ram gives Shakil a start of 200m and beats him by 1 minute.Next Ram gives shakil a start of 6 min and is beaten by 1000 meters . Find the time in minutes in which Ram and Shakil can run the race seperately.
Choices
A) 12.18 B) 10.18 C) 10.12 D) 8.1 E) 8.2
LET r be velocity of ram and s be the velocity of Shakil then (2000/r)=(1800/s)-60......(1)   second case distance Shakil travel in 6 min=360s   again equating time for both 1000/r=(2000-360s)/s.......(2)   solving (1) &amp;(2) we get   s=20/6   putting value in first we get time =480sec=8min   ANSWER:8.1
<result>D</result>
