The hcf of two numbers is 23 and the other two factor

  1. 👉  The H.C.F. of two numbers is 23 and the other two factors of their L.C.M. are 13 and 14. The larger of the two numbers is:

  1. 276

  2. 299

  3. 322

  4. 345

  1. 👉  Answer & Explanation:

    H.C.F. of two numbers is 23       [ Given ]

    Clearly, the numbers are (23 x 13) and (23 x 14).

    ⇒  Larger number will be= (23 x 14) = 322.

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:

    Total Distance Covered = (240 x 5) = 1200 km.

    Speed Formul = Distance/Time

    Speed = 1200 / (5/3) km/hr

    Required Speed = 1200 x (3/5) km/hr

                                = 720 km/hr

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
