    3333
    3225
    3200
    Option D
    Required difference = 21285 – 18060 = 3225

     

  3. Find the percentage of the total number of Hindi newspapers sold by firm D in both cities together with respect to the total number of newspapers sold in both cities.
    62%
    40%
    58%
    49%
    50%
    Option C
    Required% = [28210+24820]/[54250+36500]*100 = 58.4% == 58%

     

  4. Find the difference between the numbers of Hindi newspapers sold by firm A in Lucknow and the numbers of Hindi newspapers sold by firm B daily in Lucknow.
    5550
    5000
    5780
    5460
    5985
    Option D
    Required difference = 17460 – 12000 = 5460

     

  5. Find the average number of English newspaper sold each firm in Lucknow.
    11250
    10952
    11250
    10000
    21500
    Option B
    Required average = (6750+6790+18060+11680+11480)/5 = 10952

     

  6. A shopkeeper marks up an item of cost price Rs.1800 by (x+2)% and sells it at a discount of (x-3)% and in the whole transaction, he makes neither profit nor loss. Find the value of x.
    10
    20
    15
    12
    23
    Option E
    MP = 1800*(100+x+2)% = 18(102+x)
    SP = MP – Discount = 18(102+x) – 18(102+x)*(x-3)% Now, 18*(102+x){1-(x-3)% } – 1800 = 0
    => (102+x){1-(x-3)%} = 0
    =>x^2 – x -506 = 0
    => x^2 – 23x + 22x – 506 = 0
    => x = 23

     

  7. The ratio of the number of males and females in a company is 9:5 resp. If the number of males is increased by (x+10)% and the number of females is increased by (x+5)%, then the ratio of males and females in the company becomes 15:8 resp. Find the value of x.
    11
    10
    15
    12
    13
    Option C
    [9*(100+x+10)%]/[5*(100+x+5)%] = 15/8
    => [3*(110+x)]/[5(105+x)] = 5/8
    => x = 15

     

  8. A 240 m long train can cross a platform of 319 m in 43 seconds. If ‘x’ new number of bogies of length 69 m each are attached to the train, then the train will be able to cross a man standing on the platform in 45 seconds. Find the value of x.
    2
    6
    5
    4
    3
    Option C
    [240+319]/speed = 43
    =>speed = 13 m/s Also, [240+x*69]/13 = 45
    => x = 5

     

  9. The average weight of a class of (x+6) students is (x+1) kg. If 7 new students of average weight (x+7) kg join the class, the average weight of the class is increased by 0.7 kg. Find the value of x.
    30
    47
    36
    44
    46
    Option B
    Total weight of the class = (x+6)*(x+1) kg
    Weight of new students = 7*(x+7) kg
    Now, [(x+6)(x+1)+7(x+7)]/[(x+6)+7] = (x+1)+0.7
    => x = 47

     

  10. In a 1000 m race , A beats B by 100 m and A beats C by 200 m or 50 seconds. Find the speed of B.
    4.7m/s
    6.2 m/s
    3.2 m/s
    4.5 m/s
    5.5 m/s
    Option D
    1000/A = (1000-100)/B => A:B = 10:9 And 1000/A = (1000-200)/C
    => A:C = 5:4
    So, A:B:C = 10:9:8 1000/A = 1000/C -50
    => 1000/(10/8)C = 1000/C – 50
    => C = 200/50 = 4 m/s
    Speed of B = 9/8*4 = 4.5 m/s
