  3. 16 workers working 6 hours a day can build a boundary of length 150 metres, breadth 20m and height 12 m in 25 days. In how many days 12 workers, working 8 hours a day can build a wall of length 800 m, breadth 15 m and height 6 m.

    Use this formula =( L1 B1 H1 )/(L2 B2 H2) = (M1 D1 T1)/(M2 D2 T2)
    (150*20*12)/(800 *15* 6) = (16*6*25)/(12*8*D2)
    => D2 = 50 days
  4. A rectangular lawn is 18m * 12 m . It has a gravel path 1.5 m wide all around it on the outside. What is the area of the path.
    A)  70
    B) 88
    C) 75
    D) 99
    E) 95
    View Answer
      Option D
    Area of the lawn = 18*12 = 216 m^2
    Total area = (lawn + path) = 21*15 = 315 m^2
    Area of path = 31-216 = 99 m^2
  5. Amit covers a certain distance with his own speed , but when he reduces his speed by 10km/hr his time duration for the journey increases by 40 hours, while if he increases his speed by 5 km/hr from his original speed he takes 10 hours less than the original time taken . Find the distance covered by him.
    A) 1500km
    B) 2000km
    C) 800km
    D) 1100km
    E) 1800km
    View Answer
      Option A
    Let dist. be x km and speed be y km/h .
    [x/(y-10)] –(x/y) = 40
    => x= 2y(y-10)——–(1)
    and (x/y) – x/(y+5) = 10
    => x= 2y(y+5)———(2)
    On solving (1) and (2) , we get
    y = 25km/hr and x = 1500 km/hr
  6. Smallest side of a right angled triangle is 8 cm less than the side of a square of perimeter 56cm . Second largest side of the right angled triangle is 4cm less than the length of rectangle of area 96 cm^2 and breadth 8 cm. What is the largest side of the right angled triangle?
    A) 8cm
    B) 12cm
    D) 10cm
    E) 13cm
    View Answer
      Option D
    side of a square = Perimeter /4  = 56/4 =14 cm
    smallest side of the right angled triangle = 14-8 =6 cm
    length of the rectangle= Area / breadth = 96/8 = 12cm
    second side of the triangle= 12 – 4 = 8cm
    Hypotenuse of the right angled triangle = √(6)^2+(8)^2 = 10cm
  7. The age of Rama and Krishna are in the ratio of 7:10 resp. After 6 years the ratio of their age will be 17:23. What is the difference in their age?

    E) 16 years
    View Answer
      Option D
    After 6 years = (7x+6)/(10x+6) = 17/23
    => x =4
    Required difference = 10x – 7x = 3x = 3*4 = 12 years

    => x = 150 m

  8. Thanks for revealing your ideas right here. The other matter is that whenever a problem occurs with a laptop motherboard, individuals should not take the risk with repairing that themselves for if it is not done correctly it can lead to irreparable damage to the complete laptop. It is usually safe to approach a dealer of any laptop with the repair of its motherboard. They’ve got technicians who may have an skills in dealing with laptop computer motherboard problems and can get the right analysis and perform repairs.

  9. Amazing things here. I’m very satisfied to see your post.

    Thanks so much and I am looking forward to touch you. Will you please drop me a e-mail?
