A father said to his son I was as old as you

  1. 👉  A father said to his son, "I was as old as you are at the present at the time of your birth". If the father's age is 38 years now, the son's age five years back was:

  1. A. 14 years   

  2. B. 19 years

  3. C. 33 years

  4. D. 38 years

  1. 👉 Answer & Explanation:

    Suppose the son's current age is x years. Then, (38 - x) = x

    ⇒  2x = 38.

     â‡’ x = 19.

     Son's age 5 years back (19 - 5) = 14 years

Mr Thomas invested an amount of Rs 13900

  1. Mr. Thomas invested an amount of Rs. 13,900 divided in two different

    Mr. Thomas invested an amount of Rs. 13,900 


  2. 👉  Mr. Thomas invested an amount of Rs. 13,900 divided in two different schemes A and B at the simple interest rate of 14% p.a. and 11% p.a. respectively. If the total amount of simple interest earned in 2 years be Rs. 3508, what was the amount invested in Scheme B?

  1. A. Rs. 6400

  2. B. Rs. 6500

  3. C. Rs. 7200

  4. D. Rs. 7500

  1. 👉 Answer & Explanation:

    Suppose the Thomas invested sum in Scheme A is Rs. X and that in Scheme B is Rs. (13900 - X)

    Then, { (X x 14 x 2) / 100 } + {(13900-X x 11 x 2) / 100} = 3508

    ⇒ 28X -  22x = 350800 - (13900 x 22)

    ⇒ 6X = 45000

    ⇒ X = 7500.

    So, invested sum in Scheme B = Rs. (13900 - 7500) = Rs. 6400.

An aeroplane covers a certain distance at a speed of 240 kmph

  1. 👉 An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1 hours, it must travel at a speed of:

  1. A. 300 kmph

  2. B. 360 kmph

  3. C. 600 kmph

  4. D. 720 kmph

  1. 👉 Answer & Explanation:

A train 125 m long passes a man running at 5 km/hr

  1. 👉   A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is  going, in 10 seconds. The speed of the train is:

  1. A. 45 km/hr

  2. B. 50 km/hr

  3. C. 54 km/hr

  4. D. 55 km/hr

  1. 👉  Answer & Explanation:

    Relative Speed of Train respective to Man : (125 / 10) m/sec

    = 12.5 m/sec   [ As we Know to convert m/sec -> km/hr we must multiply with 18/5 ]

    = 12.5 x (18/5) km/hr

    = 45 km/hr

    Consider the spped of the train is X km/hr then Relative speed of Man will be X-5 km/hr

    So,   X - 5 = 45 

    X = 50 km/hr
