    On the basis of given table in question ,
    The income from miscellaneous = 15 thousands
    The income from the donation = 60 thousands

    Required percentage =
    The income from the donation
    × 100 %
    The income from miscellaneous

    Correct Option: D

    On the basis of given table in question ,
    The income from miscellaneous = 15 thousands
    The income from the donation = 60 thousands

    Required percentage =
    The income from the donation
    × 100 %
    The income from miscellaneous

    Required percentage =
    60
    × 100 = 400%
    15


Direction: The following questions are based on the table given below which represents the distance (in km) travelled by two persons A and B in the same direction :

  1. The distance between A and B is maximum at the end of

    As per the given above table , we see
    Distance after 2 hours = 65 – 50 = 15 km
    Distance after 3 hours = 100 – 70 = 30 km
    Distance after 4 hours = 125 – 85 = 40 km

    Correct Option: D

    As per the given above table , we see
    Distance after 2 hours = 65 – 50 = 15 km
    Distance after 3 hours = 100 – 70 = 30 km
    Distance after 4 hours = 125 – 85 = 40 km
    Distance after 5 hours =160 – 110 = 50 km (maximum distance)
    Thus , required answer is 5 hours .



  1. What is the distance (in km) between A and B at the end of 8th hour?

    According to given table, we have
    Total distance travelled in first eight hours by B = 25 + 40 + 35 + 25 + 35 + 10 + 25 + 15 = 210 kms
    Total distance travelled in first eight hours by A = 20 + 30 + 20 + 15 + 25 + 15 + 25 + 35 = 185 kms
    ∴ Required distance = Total distance travelled in first eight hours by B - Total distance travelled in first eight hours by A

    Correct Option: B

    According to given table, we have
    Total distance travelled in first eight hours by B = 25 + 40 + 35 + 25 + 35 + 10 + 25 + 15 = 210 kms
    Total distance travelled in first eight hours by A = 20 + 30 + 20 + 15 + 25 + 15 + 25 + 35 = 185 kms
    ∴ Required distance = Total distance travelled in first eight hours by B - Total distance travelled in first eight hours by A
    Required distance = 210 – 185 = 25 km


  1. The ratio of A’s speed during the first five hours and the last five hours is

    From the given above table ,
    Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
    Total time taken = 5 hours
    Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
    Total time taken = 5 hours

    Required ratio =
    Total distance travelled in first five hours by A
    :
    Total distance travelled in last five hours by A
    Total time takenTotal time taken

    Correct Option: B

    From the given above table ,
    Total distance travelled in first five hours by A = 20 + 30 + 20 + 15 + 25 = 110 kms
    Total time taken = 5 hours
    Total distance travelled in last five hours by A = 15 + 25 + 35 + 20 + 30 = 125 kms
    Total time taken = 5 hours

    Required ratio =
    Total distance travelled in first five hours by A
    :
    Total distance travelled in last five hours by A
    Total time takenTotal time taken

    Required ratio of average speed =
    110
    :
    125
    = 110 : 125 = 22 : 25
    55



  1. B’s average speed (km/hour) during the first four hours is

    On the basis of given table in question ,
    Total distance travelled in first four hours by B = 25 + 40 + 35 + 25 = 125 kms
    Total time taken = 4 hours

    B’s average speed = Total distance travelled in first four hours by Bkmph
    Total time taken

    Correct Option: C

    On the basis of given table in question ,
    Total distance travelled in first four hours by B = 25 + 40 + 35 + 25 = 125 kms
    Total time taken = 4 hours

    B’s average speed = Total distance travelled in first four hours by Bkmph
    Total time taken

    B’s average speed = 25 + 40 + 35 + 25kmph = 31.25 kmph
