**Direction (9-10): Study the following information and answer the questions that follow:**

There are three cars A, B and C with different maximum speed. The minimum speed of these cars is 0 kmph and the maximum speed is marked in the speedometer of these cars. Rest of the speeds are marked at equal intervals in the speedometer. The table below shows the maximum speed of the car and the number of points marked in the speedometer of the car. The first point in the speedometer represents Speed of 0 kmph and the last point represents the maximum speed.

(Example: If the maximum soeed of the car is 100 kmph and there are 11 points marked in the speedometer then each point represents an increase of 10kmph with 1^{st} point as 0 kmph).

- What is the difference in time taken by Car A to cover 80 Km when it moves at a constant speed and the pointer of the speedometer throughout the journey points at the 5
^{th}position (5^{th}point) and the time taken by Car C to cover 100 km when moving at a constant speed with the pointer of the speedometer pointing at point 7?

A) 20 minutes

B) 40 minutes

C) 50 minutes

D) 30 minutes

E) 1 hour

- Car B has to cover a distance of 210 km in 3 hours. It travels for some distance at a constant speed of 60 kmph for 90 miniutes. At what position will the pointer of the speedometer point throughout the second part of the journey if the car B travels at a constant speed and reaches the destination on time.

A) 15

B) 16

C) 17

D) 18

E) 19

thanks Team

but these are very tough how to solve faster 🙁

first focus on solving;; if you are able to solve it then its good,, then keep on practicing, your speed will get improved automatically.

Okay thnkyou?

Que 6

Diff D&E it is 16

16/100*176000

176000*16/25=

16/25 how?

it is diff. not take ratio

16/100 is right

Naah because 176000 equal to 25%

and D & E diff 16

so 17600*16/25=

nahi dear 176000 are total no. of population of state

see (35/100*25/100-35/100*20/100)*x=3080

x=176000 which means total no. of population

hence diff asked get it 16/100*176000=ans

Oh Haan you’re right

176000 total population h

hmm

yes necessary changes made

In Q.9

Time difference= 80/40 *60 -100/60*20 =120-100=20 minutes

how (100/60*20) will come?

100 – distance

60 – speed

20 – ????

ma’am please help

Time has been multiplied by 60 to convert it into minutes

T=D/S

= 80/40 *60 – 100/60 *60

please elaborate Q 10

see once more,, a line was missed while typing..edited

in que 10 how average taken 70km/hr it is total speed??

see ques 10 again;; edited now

thx sir

refresh once more for the edited answer of Ques 10

arre mtlab 210km ko 3hr mein done karna ab 210/3=70km

ab ye step karo ya na karo , koi fayda nahi

@TheSDixit:disqus comment post nahiho raha

haan?

@surajskt:disqus sir correct hai que 10 thx sir

sir speedometer mn 16 points means?????

for which car? A or B?

For A it is the maximum speed i.e 150 kmph

For B 16th point means- first remove the 1st pointer i.e the pointer with speed 0 from this 16 i.e remaining pointer showing actual speed= 15

so speed at pointer 16= 15* 180/(37-1)= 75 kmph

sir @surajskt:disqus in question no 5..in explanation u hv written 16*11000..sir it should be 25*11000..plz check..

25/100 * 25/100 * x = 11000

1/4 * 1/4 * x = 11000

So x = 11000 × 16

bt why two times 25/100

because city L is in State B

when total population = x

then state B= 25/100 x

and hence city L= 25% of this 25/100 x

ty sir ji

8/10..sir Q9 me C ya B?B lene se 80min aa rha h

Yes it should be C

ty ty

Good DI sets, especially 9 nd 10 loved it!

good sets

In question no. 7 why we can’t use previous question data ?? If we, then it can be answered.

If it is mentionedn Q to use previous Q’s data, then only you can use. Otherwise not

Thanks for giving your ideas listed here. The other factor is that when a problem takes place with a laptop or computer motherboard, people today should not take the risk regarding repairing that themselves because if it is not done correctly it can lead to permanent damage to the entire laptop. It’s usually safe to approach any dealer of your laptop for that repair of that motherboard. They have technicians with an competence in dealing with laptop computer motherboard issues and can make right prognosis and accomplish repairs.
