Interview Questions.

Q1. As may be obvious, The Number 15 Requires 17 Steps To End Up At 1.of The Numbers Not Greater Than 50,which Takes The Longest To Reach The Number 1 ?
27, which makes 111 strides

Q2. On the off chance that Log2 X - 5 Log X + 6 = 0, What Would The Value/Values Of X Be?
Log2 x means (log x)^2,

The response can be found by making the replacement y = log x to give

y^2 - 5y + 6 = 0, which gives the arrangements

y = 3

y = 2

ie., log x = 2 or log x = 3

ie., e2 or e3

Q3. Could You at any point Tender A One Rupee Note In Such A Manner That There Shall Be Total 50 Coins But None Of Them Would Be 2 Paise Coins.?
In diving request,

it are accessible to utilize categories of 1p,5p,10p,25p which.

In this way,

25p coins : 1

10p coins : 2

5p coins : 2

1p coins : 45

Q4. A Sum 's' Is Divided Into 4 Parts. Second Person Gets Rs 10 More Than First.3rd Person Is Rs 10 More Than Second, fourth Is 10 More Than third. The Amount Do first Person Get.?
first individual gets Rs.(s-60)/4

Allow us to accept that first individual gets Rs.x

Then second will get Rs.x+10

third will get Rs.x+20

fourth will get Rs.x+30

Then the total s=x+(x+10)+(x+20)+(x+30)

=> s=4x+60

=> 4x=s-60

=> x=(s-60)/4

In this way first pesron will get (s-60)/4

Q5. The Minute Hand Of A Clock Overtakes The Hour Hand At Intervals Of 64 Minutes Of Correct Time. The amount A Day Does The Clock Gain Or Lose?
Straightforward clarification by Juned:

The moment hand overwhelms hours hand multiple times in 12 hours

In this way the time required continuously to overwhelm = (12 * 60)/11

                                                                           = 65.4545 minutes

In this clock the moment hand is requiring 64 minutes to surpass

Hence in 12 hours it will surpass 720/64 = 11.25 times

That implies 0.25 times more in 12 hours or 0.5 times more in a day

Henceforth, the clock gains = 0.5 seasons of the typical time

⇒ 65.4545 * 0.5 = 32.72 minutes or 360/11 minutes

Clarification by a4academics

Let

x be distance gone by hour hand

Then distance went by minute hand = 1 + x

Time = Distance/Rate

⇒ x/(1/12) = (1 + x)/1

⇒ x = (1/12)(1 + x) = 1/12 + x/12

⇒ (11/12)x = 1/12

x = 1/11

Compute time for minute hand to travel a distance 1 + x.

Time = Distance/Rate

(1 + x)/1 = 1 + x = 1 + 1/11 = 12/11 hour

Real opportunity to overwhelm on clock is 64 minutes.

64 min = 64/60 hours = 16/15 hour

Right Clock Speed/Actual Clock Speed

(12/11)/(16/15) = 12*15/(11*16) = 180/176 = 45/44

The clock gains:

45/44 - 1 = 1/multi day = 24/44 hour = 6/11 hour = 360/11 min

= 32 min and 434/11 sec.

Q6. Three Containers A, B And C Have Volumes A, B, And C Respectively; And Container An Is Full Of Water While The Other Two Are Empty. On the off chance that From Container?
a , we need to take away

b/3 and c/2

so water left in compartment A

= a - (b/3 + c/2)

Q7. 1/8 Is Divided By 's' , If 's' Is Increased By 2 Times, What Is The Result?
Reply = 1/(8s/2)

= 1/4s

Increments twice

Q8. Complete The Sequence A, E ,I ,m ,q ,u , _ , _?
Y,C

After each character +3

Q9. 9 Laboures Can Complete The Construction Of A Wall In 18 Days. What number of Less Days Will 12 Laboures Take To Complete The Same Wall?
Work done by a solitary individual = 1/( 9* 18) = 1/162

Work done by 12 individuals = 12/162

Time taken to complete work = 162/12 = 13.5

Q10. The Ratio Between Two Numbers Is 5:7 And Their Product Is 56
From the above data

x/y = 5/7

xy = 560

Tackling the above condition we get the numbers as 20 and 28

Contrast is 8

Q11. The Average Age Of 10 Members Of A Committee Is The Same As It Was 4 Years Ago, Because An Old Member Has Been Replaced By A Young Member.find How Much Younger Is The New Member ?
Allow the individuals to be Old Having age O + other 9 having ages x and New one having age Y

Amount of their ages = (Y + 9 × x) and normal = (Y + 9 × x)/10

Before 4 years total was (O + 9 x - 10 × 4) and normal = (O + 9 x - 10 × 4)/10

likening, Y + 9 x = O + 9x - 40

Y = O - 40

More youthful is 40 years more youthful than Old one.

Q12. One Dog Tells The Other That There Are Two Dogs In Front Of Me. The Other One Also Shouts That He Too Had Two Behind Him. What number of Are They?
canine

canine

canine

So there are 3 canines

Q13. A Certain Type Of Mixture Is Prepared By Mixing Brand An At Rs.9 A Kg. With Brand B At Rs.4 A Kg. In the event that The Mixture Is Worth Rs.7 A Kg., How Many Kgs. Brand An Are Needed To Make 40kgs. Of The Mixture?
A + B = 40.

Also, at Rs 7 a kg for 40 kg, you need a sum of Rs.280.

So the subsequent condition is 9A + 4B = 280

From the principal condition: B = 40 - A

furthermore, sub into the subsequent condition:

9A + 4(40-A) = 280

9A + 160 - 4A = 280

5A = 120

A = 24.

Your response, obviously, is A = 24.

Q14. A Person Was Fined For Exceeding The Speed Limit By 10 Km/hr. Someone else Was Also Fined For Exceeding The Same Speed Limit By Twice The Same. On the off chance that The Second Person Was Traveling At A Speed Of 35km/
1 individual surpassed by 1@Another individual two times 10 which is 2@Given he is going at 35 km/h. So speed limit is 35 - 20=15 km/hr

Q15. Track down The Next Number In The Series 1, 3 ,7 ,13 ,21 ,31?
k(n) = k(n-1) +2(n-1) with

k(1) =1

k(7) =k(6) +2(7-1)

k(7) =31 +2*6

k(7) =31+12

k(7) =43
