Question 19. A Train Running At Speed Of 126 Kmph. What Will Be The Length Of Train If It Cross A Tree In 5 Sec.

Answer :

Formula Used: Distance = (Speed * Time)

convert the educate pace (Kmph) in to mps multiply by 5/18

velocity (mps) = 126 * five/18 = 35 mps 

period = ( 35 * five ) meter

= one hundred seventy five meter

Question 22. A Train Overtakes Two Persons Who Are Walking In The Same Direction In Which The Train Is Going, At The Rate Of 2 Kmph And four Kmph And Passes Them Completely In 19 And 20 Seconds Respectively. The Length Of The Train Is:

Answer :

Convert the persons Speed in m/sec

2 kmph = (2 x 5/18) m/sec = 5/nine m/sec.

Four kmph = (4 x five/18 m/sec = 10/nine m/sec.

Let the period of the educate be x meters and its speed with the aid of y m/sec.

Relative pace in respect to each man or woman (y - 5/9) and (y - 10/nine)

Formula Used: Time = Distance / velocity 

so x / (y - 5/nine) = 19 ---- (1)

and x / (y - 10/9) = 20 ---- (2)

9x = 19 (9y - five) ----- (1)

9x = 20 (9y - 10) ------(2)

locate the value of x and y 

19 (9y - five) = 20(9y - 10) 

171 y - 95 = 180 y -two hundred => 9y = 105 => y = one hundred and five/9 = 35/3

Now discover the price fo x by above any equations 

9x = 171 *35/three - 95 = 57 *35 - 95

9x = 1900 => x = 211.1 meter

Question 23. Ajay, Vijay And Sanjay Rent A Pasture. Ajay Puts 10 Oxen For 7 Months, Vijay Puts 12 Oxen For five Months And Sanjay Puts 15 Oxen For three Months For Grazing. If The Rent Of The Pasture Is Rs. One hundred seventy five, How Much Must Sanjay Pay As His Share Of Rent ?

Question 24. A Train Overtakes Two Persons Walking Along A Railway Track. The First One Walks At four.Five Km/hr. The Other One Walks At 5.4 Km/hr. The Train Needs 8.Four And 8.5 Seconds Respectively To Overtake Them. If Both The Persons Are Walking In The Same Direction As The Train? So What Is The Speed Of The Train ?

Answer :

Convert the Speed in m/sec

so 4.5 km/hr = ( 4.5 x five/18 ) m/sec = five/4 m/sec = 1.25 m/sec,

and 5.4 km/hr = ( 5.4 x five/18 ) m/sec = 3/2 m/sec = 1.Five m/sec.

Here count on the velocity of the teach as x m/sec. 

So relative will be (x-1.25) and (x - 1.Five) 

(x - 1.25) x eight.Four = (x - 1.5) x eight.Five

=> 8.4x - 10.Five = eight.5x - 12.Seventy five

=> zero.1x = 2.25 

=> x = 22.5 m/s

As options are given in km/hr so convert the rate mps to kmph

So Speed of the train = ( 22.5 x 18/five ) km/hr = 81 km/hr.

Question 25. X And Y Started A Business Together. If X Invested Rs. 16,000 For 8 Months And Y Invested Some Amount In The Business For four Months. If Y Claims 2/7 Of The Total Profit Earned. How Much Money Was Invested By Y?

Answer :

Lets assume the overall income = Rs. T

so Y part = 2*T/7 and

X component = T - 2*T/7 = 5*T/7

X, Y ratio

=> X : Y = 5*T/7 : 2*T/7 = 5 : 2

Y invested Rs.P

so (16000 * eight) / (P * 4) = 5/2

=> P = (16000 * 8 * 2) /(5 * 4)

=> P = Rs. 12800
