pramod sharma  (10 years ago)

answer of the above question is none of them.....
let P-------------Q now bhaskar has speed of 20 km/p so it takes 5h to reach Q from p for bhskar but the speed of kiran is 50 km/p so he takes only 2h to reach p from q....when kiran is on p,at that time bhaskar is only 40 km from p and walking towards q....now for the second time, let at a distance of x km from P they meet thereore...kiran has to cover whole x km in the same time as bhaskar covers x-40 km...now...(x-40)/20 =x/50.....gives x=200/3 km from P...therefore distance from Q is 100-x= 100-200/3 = 100/3 = 33.33 km

Time taken by Kiran to reach P= 2hrs
=>Distance covered by bhaskar in 2 hrs= 40kms
Now appliying relative motion concept
Kiran has to cover 40 kms with speed of (50-20)km/hr=30 km/hr( because both are moving in same direction)

=> Distance to be covered = 40kms
Speed = 30 km/hr
=>time taken =40/30 hrs=1.33hrs

Total distance covered by bikram in this time at 20 km/hr=40kms+20*1.33kms
=66.66kms
=> distance from point q =100-66.66 = 33.33kms
