    10
    14
    15
    Option E
    [12*(385-?^2)]/16 =120
    => 385 – ?^2 = 160
    => ?^2 = 225
    =>? = 15

     

  2. ? = 40% of 65% of 1800 +5^2
    465
    484
    493
    444
    400
    Option C
    ? = 40% of 65% of 1800 +5^2
    => ? = 468 + 25
    => ? = 493

     

  3. ? = [(6^3 + 8^2)/8]^2/35
    30
    35
    25
    32
    28
    Option B
    ? = [(6^3 + 8^2)/8]^2/35
    => ? = [( 216+64)/8]^2/35
    => ? = 35^2 /35
    => ? = 35

     

  4. ? = 30% of (18^2 + 6) + 72% of 1200
    920
    858
    890
    963
    900
    Option D
    ? = 30% of (18^2 + 6) + 72% of 1200
    => ? = 0.3 * 300 + 0.72 *1200
    => ? = 99+864
    => ? = 963

    100
    185
    120
    150
    130
    Option D
    X = 12*5/18*45
    => x = 150 metres

     

  7. Vijay can complete a work in 24 days while Arjun can complete the same work in 15 days. If both worked together , then find the time taken to complete 86(2/3)% of the work.
    6 days
    8 days
    4 days
    5days
    7 days
    Option B
    LCM (24 and 15) = 120 units
    Required time taken = 86(2/3)% of 120/13 = 8 days

     

  8. The average of weights of x,y and z is 50 kg and the average of weights of y and z is 45 kg. If the weight of w is 30 kg, then what is the average weight of x and w ?
    45 kg
    33 kg
    50 kg
    25 kg
    40 kg
    Option A
    (x+y+z)/3 = 50 (y+z)/2 = 45
    => y+z = 90 (x+90)/3 = 50
    => x =60 kg
    Required average = (60+30)/2 = 45 kg

     

  9. Pipe A can fill a bucket 4 times faster than another pipe B and takes 15 minutes less than pipe B to fill the bucket. If both the pipes are opened simultaneously, then find the time taken to fill the bucket.
    4
    8
    6
    7
    5
    Option A
    Let time taken by pipe A to fill the bucket alone be x minutes. 4x-x = 15 => 3x = 15 => x = 5 Time taken by B = 20 minutes
    Time taken by A = 5 minutes
    Required time taken by both pipes simultaneously to fill the bucket
    = 1/{1/5+1/20} = 4 minutes

     

  10. The selling price of 25 articles is same as the cost price of x articles. Find the value of x if the profit earned is 40%.
    28
    20
    15
    35
    22
    Option D

    SP of 25 articles = Rs. 25
    CP of x articles = Rs. 25
    Profit earned = 40% 40/100 = (x-25)/25
    => x = 35
