  6. A,B and C are colleagues. Find the age of A.
    Statement I: B is 16 years older than C and A is 6 years younger than B. After 4 years, the respective ratio of the ages of A and B will become 20:23.
    Statement II: Average of age of A,B and C is 34 years 8 months. Age of A is 10 years more than age of C.

    II is alone sufficient not I.
    Either I or II.
    I is alone sufficient not II.
    Neither I nor II.
    Both I and II.
    Option C
    From I: Let the age of C be x years.
    Age of B = x+16 years Age of A = x+10 years
    Now, (x+16+4)/(x+10+4)= 23/20
    => x = 26
    Age of A = 36 years I alone is sufficient to answer the question.
    From II: Let the age of C be y years.
    Age of A = y+10 years
    Let the age of B be z years.
    So,y+y+10+z = 104
    II alone is not sufficient to answer the question.

     

  7. 480 litres of mixture of milk and water is poured in a vessel of sufficiently large quantity (x+20) litres of water is added to the vessel. Find the value of x.
    Statement I: Ratio of milk to water in the initial mixture is 7:5 resp. and ratio of milk to water in the final mixture is 14:13 resp.
    Statement II: Final quantity of mixture in the vessel was (500+x) litres.

    Neither I nor II.
    Either I or II.
    II is alone sufficient not I.
    I is alone sufficient not II.
    Both I and II.
    Option D
    From I:
    Quantity of the mixture in the vessel initially = (7/12)*480 =280 litres and initial quantity of water in the vessel = 200 litres
    Now, 280/(200+x+20)=14/13
    => x = 40
    I is alone sufficient to get the answer of the question.
    From II: 480+(x+20) = (500+x)
    II alone is not sufficient to get the answer of the question.

     

  8. A bag contains (x-2) black balls, (x+4) white balls, and (x+8) brown balls. Find the number of balls in the bag.
    Statement I: The ratio of number of black balls to the number of white balls in the bag is 8:11.
    Statement II: The total number of balls In the bag is 4 times the number of black balls in the bag.

    Both I and II.
    II is alone sufficient not I.
    Either I or II.
    I is alone sufficient not II.
    Neither I nor II.
    Option C
    Total number of balls in the bag =(x-2)+(x+4)+(x+8) = 3x+10
    From I: (x-2)/(x+4) = 8/11
    =>x = 18
    Total number of balls in the bag = 3*18+10 = 64
    I is alone sufficient to get the answer of the question.
    From II: 3x+10 = 4(x-2)
    => x = 18
    Total number of balls in the bag = 3*18+10 = 64
    II is alone sufficient to get the answer of the question.
    Either I or II alone sufficient to get the answer of the question.

     

  9. There are three pipes A,B and C. Two of them are inlet pipes and one is outlet pipe. Which pipe is outlet pipe?
    Statement I: A and B can fill the tank in 20 minutes while B and C can fill the tank in 30 minutes.
    Statement II: A and C together can fill the tank in (20/3) minutes.

    Both I and II.
    Neither I nor II.
    Either I or II.
    II is alone sufficient not I.
    I is alone sufficient not II.
    Option A
    From I: Total work LCM(20 and 30) = 60 units
    Number of units of water filled by A and B together in one minute = 60/20 = 3 units
    Number of units of water filled by C and B together in one minute = 60/30 = 2 units
    I alone is not sufficient to get the answer of the question.
    From II: II alone is not sufficient to get the answer of the question.
    Combining I and II, we get Total work LCM(20 and 30) = 60 units
    Number of units of water filled by A and B together in one minute = 60/20 = 3 units
    Number of units of water filled by C and B together in one minute = 60/30 = 2 units
    Number of units of water filled by C and A together in one minute = 60/(20/3) = 9 units
    Number of units of water filled by (A+2B+C) in one minute = 3+2 = 5 units
    Now, A+2B+C = 5 =>9+2B = 5
    =>B = -2
    B is outlet pipe.

     

  10. What is the time taker by train to travel form Delhi to Chandigarh. The distance between Delhi and Chandigarh is 270 km.
    Statement I: Time taken by train to cross a platform of length 350 m is 40 sec.
    Statement II: Time taken by train to cross a man standing on platform is (50/3) sec.

    Neither I nor II.
    I is alone sufficient not II.
    Both I and II.
    Either I or II.
    II is alone sufficient not I.
    Option C
    Let length and speed of the train be “l” m and “s” m/s resp.
    From I: (I+350)/s = 40
    I alone is not sufficient to get the answer of the question.
    From II: I/s = 50/3
    II alone is not sufficient to get the answer of the question.
    Combining I and II , we get
    (50s/3)+350 = 40s
    => s = 15 m/s = 54 km/hr.
    Required time = 270/54 =5 hours
