2 trains starting at the same time from 2 stations 200 km apart and going in opposite direction cross each other at a distance of 110 km from one of the stations. What is the ratio of their speeds?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    If the trains cross each other at a distance of 110 km from one of the stations, at same time, they cover 110 km & 90 km respectively

    so ratio of their speed =110: 90 = 11: 9

 Excluding stopages, the speed of a bus is 54 kmph and including stopages, it is 45 kmph. For how many minutes does the bus stop per hour?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    Due to stoppages, it covers 9 km less.\n\nTime taken to cover 9 km = (9/54 x 60) min = 10 min.

Two boys starting from the same place walk at a rate of 5 kmph and 5.5 kmph respectively. What time will they take to be 8.5 km apart, if they walk in the same direction?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    The relative speed of the boys = 5.5 kmph – 5 kmph = 0.5 kmph

    Distance between them is 8.5 km

    Required time = 8.5km / 0.5 kmph = 17 hrs

 If train runs at a speed of 48 kmph on an average, a train covers a distance in 50 min, the train must run to reduce the time of journey to 40 min will be, at which speed?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    Present Time = 50 mins

    Converting into hour format --> 50/60 hr = 5/6 hr

    Present Speed = 48 kmph

    Therefore, distance = S*T = 48 * (5/6) = 40 km

    To run in 40 min, time = 40/60 hr = 2/3 hr

    Required speed = Distance/ time = 40 * (3/2) kmph = 60 kmph

A snail is at the bottom of a 20 meters deep pit. Every day the snail climbs 5 meters upwards, but at night it slides 4 meters back downwards. How many days does it take before the snail reaches the top of the pit?

  • a
  • b
  • c
  • d
  • OOPS, your answer is incorrect

    Since the snail moves up 1 meter a day (5 meters upwards, but at night it slides 4 meters back downwards) so it will reach 15 meters in 15 days.

    Next day it will again climb 5 meters upward and reaches the top. (During daytime itself)
