@veertamizhan said:A train meets with an accident 150 km from the originating station. It completetd the remaining journey at half of the usual speed and reached an hour late at the destination. Had the accident took palce 30 km later, it would have been only half an hour late. Find the distance between the two stations.
@EagleMenace said:No need of any calculation.The answer is given in statement. Statement says it would have taken 30 mins less if accident had taken 30 km later, that means the distance he needs to travel to reach station is 60 km, hence he is taking 60 mins..So total distance is 150+60=210km

Duels in the town of discretion are rarely fatal. There, each contestant comes at a random moment between 5 a.m. and 6 a.m. on the appointed day and leaves exactly 5 minutes later, honor served, unless his opponent arrives within the time interval then they fight. What fraction of duels lead to violence? ..

@nole said:Ashish is studying late into the night and id hungry . He opens his mother's snack cupboard without switching on the lights . Knowing that his mother has kept 10 packets of chips and biscuits in the cupboards . He pulls out 3 packets from the cupboards and all of them turn out to be chips . what is the probability that the snack cupboard contains 1 packets of biscuits and 9 packets of chips ?i approached it like this.number of possible cases3chips packet 7biscuit4chips 6 biscuit5chips 5 biscuits6chips 4biscuits7chips 3 biscuits8chips 2 biscuits9chips 1biscuits10 chips 0 biscuits(although i took this case also,because in forums everyone was taking it,but when it is given 10 packets of chips and biscuits,then i think ATLEAST 1 biscuits packet must be there.isn't it?? )so my answer was 1/8,because above there are total 8 cases.but the answer is Probability = C(9, 3)/{C(10, 3) + C(9, 3) + .... + C(3, 3)} = 84/330 = 14/55.How??This was IIFT 2012 question. can anyone explain why 1/8 is wrong answer and how we got 14/55 ?

@nole said:@Torque024 yeah i have visited that link,but i didn't get the solution.Why the solution is linked to the 3 packet of chips ? that was my doubt.
