  1. A sum of money is lent out at CI at 20% p.a for 2 years.It would fetch Rs 1928 more if intrest is compunded half yearly.Find the sum?
    Rs 80000
    Rs 55000
    Rs 85000
    Rs 90000
    None of these
    Option A
    Let the sum be P.
    Intrest obtained=20+20+20*20/100=44
    Intrest on half yearly=10+10+10*10/100=21
    Again,21+21+21*21/100=46.42%
    Difference=46.42-44=2.42%
    2.41%=1928
    1%=800
    100%=80000

     

  2. How many metal spehere can be made out of solid metal cone of 28 cm high and 6 cm radius,the diameter of each radius is 3 cm?
    82
    76
    74
    80
    None of these
    Option C
    Number of spehere=Vol of cone/Vol of each spehere

     

  3. Study the following and answer the questions:

    Y=81% of (√680-√480) + 70% of (22.950 + 25.890)

    42
    35
    38
    40
    None of these
    Option C
    =81/100 *(26-22)+ 70/100*48.840
    =3.24+34.20

     

  4. 40 , 40 , 20 , 60 , 5 , 75 , ?
    12.5
    15
    13.5
    14.5
    16
    Option A
    40*1=40
    40*0.5=20
    20*3=60
    60*0.25=5

     

  5. a)x^2-31x+238=0
    b)y^2-28y+187=0
    x>y
    x
    x is less thn or equal to y
    x is greater than or equal to y
    x= y or relationship cannot be established
    Option E
    x=17,14
    y=11,17

     

  6. Akansha and Brijesh run from Point P to Point Q at distance of 1200 m at 4m/s and 5m/s respectively.Brijesh reaches Y and immeiately turns back meeting Akansha at point R.Wha is the distance from Q to R?
    400/3 m
    350/3 m
    500/3 m
    550/3 m
    None of these
    Option A
    When they meet,distance travelled=2*1200=2400 m
    Time taken=2400/(4+5)=800/3 sec
    Distance of R from P=4*800/3=3200/3 m
    Therefore,distance of R from Q=1200-3200/3=400/3 m

     

  7. A metallic spehere of diameter 12 cm is meletd and drwan into a wire of uniform cross-section.If the radius of wire is 2mm,find lenghth?
    70 m
    72 m
    75 m
    80 m
    81 m
    Option B
    Raduis of metallic wire=12/2=6
    Radius of wire=0.2 cm
    Vo of metalic spehere=4/3 * n * 6^3
    (4/3)*n*6^3 = n *0.2^2 * Lenght
    Length=72

     

  8. A sum of money amunts to Rs 189 after one year and Rs 204.12 after two years at certain rate of intrest compounded annually.What is principal amount?
