Question 1. Nine Laboures Can Complete The Construction Of A Wall In 18 Days. How Many Less Days Will 12 Laboures Take To Complete The Same Wall?

Answer :

Work finished with the aid of a unmarried man or woman = 1/ ( nine* 18) = 1/ 162

Question 2. The Rectangle Box With Square Base Is Open At The Top. The Maximum Volume Of The Box Made From 1200 M2 Tin,in M3 Is?

Answer :

Let the period be x and the breadth be y.

Now because it has a square base;

x=y

Now the floor place may be given as S= x^2+4xy (Area of rectangular base + Area of Sides)

And Volume may be given as V = x^2y

ATQ, S=1200,so 1200=X2+4xy

y=(1200-x2)/4x

Now for V to be max

V'=zero

V'(x)=x2y

Solving for x we get x=20

Now y=20m

Hence volume is 20x20x10=4000 m3

Question four. The Difference Between The Compound And Simple Interest On A Certain Sum For 2 Years At The Rate Of eight% Per Annum Is Rs.80,what Is The Sum?

Answer :

Since we recognise that SI and CI are equal for first year. Difference is due to the SI of 1st yr is dealt with as PRINCIPLE of 2nd year in CI.

So 1st we calculate the quantity which treated as P in CI

P = 100*SI/R*T = a hundred*eighty/eight*1 = a thousand

This amount is likewise the SI for 1 12 months.

SI = 1000

T = 1 Year

R = 8%

P = 100*one thousand/eight*1 = 12500

Question 9. After Spending 2/three Of His Salary On Rent And Food Items And 1/4th Of The Remaining On Transportation, Rajesh Has 6000 With Him. How Much Did He Pay On Transportation?

Answer :

Let x be the profits.

Then if he spends (2/three)x on lease and meals then the final income is x/three,

Out of which he spends 1/4 i.E(x/three)1/four or x/12 on transportation...And the amount left thereafter is : ( x/3 ) - ( x/12 ) = x/4

Given..The quantity left with Rajesh is : 6000 = x/4

=> Salary of Rajesh 'x' is : 6000 * four = Rs.24,000

Amount spent on lease and food = 24000 * (2/3) = Rs.16,000

Remaining quantity : 24000 - 16000 = Rs.8000

Amount spent on transportation : 8000 * (1/four) = Rs.2000

Remaining amount : 8000 - 2000 = Rs.6000,the amount left with Rajesh

So answer is : 2000

Answer :

1st person receives Rs.(s-60)/4

Let us assume that 1st character receives Rs.X

Then 2d will get Rs.X+10

3rd will get Rs.X+20

4th will get Rs.X+30

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

=> s=4x+60

=> 4x=s-60

=> x=(s-60)/4

Therefore 1st pesron gets (s-60)/four

Question 19. The Average Age Of 10 Members Of A Committee Is The Same As It Was four Years Ago, Because An Old Member Has Been Replaced By A Young Member.Discover How Much Younger Is The New Member ?

Answer :

Let the contributors be Old Having age O + different nine having a long time x and New one having age Y

Sum of their ages = (Y + 9 × x) and average = (Y + 9 × x)/10

Before 4 years sum changed into (O + nine x – 10 × 4) and average = (O + 9 x – 10 × 4) /10

equating, Y + nine x = O + 9x – forty

Y = O – 40

Younger is 40 years more youthful than Old one.

Answer :

PA = PB = 9 cm ( Length of tangents from an outside factor)

Angle PAB = Angle ABC ( change angles PA !! BC)

AC = AB = 6 cm

Triangles PAB and ACB are isosceles and sre comparable triangles

( They are equiangular)

Taking the ratios of respective facets

BC/AB = AC/PB

BC/6 = 6/9

BC = four cm

Question 23. A Number Of Cats Got Together And Decided To Kill Between Them 999919 Mice. Every Cat Killed An Equal Number Of Mice. Each Cat Killed More Mice Than There Were Cats. How Many Cats Do You Think There Were ?

Answer :

Observing the num 999919 which is the entire num of rats being eaten, we will write it as

(1000000-eighty one) = (a thousand^2-nine^2) = (one thousand+nine)(one thousand-nine) = (1009)(991)

So total num of rats killed =(1009)(991)

And given that every cat kills more num of rats than the entire num of cats

Hence each cat kills 1009 num of rats

And there are 991 num of cats

Question 25. The Square Of A Two Digit Number Is Divided By Half The Number. After 36 Is Added To The Quotient, This Sum Is Then Divided By 2. The Digits Of The Resulting Number Are The Same As Those In The Original Number, But They Are In Reverse Order. The Ten's Place Of The Original Number Is Equal To Twice The Difference Between Its Digits. What Is The Number?

Answer :

Let the number be 10A + B = C

now, (C^2/(C/2) + 36)/2= 10B + A

or, (2C+36)/2 = 10B + A

or C+18=10B+A

or, 10A + B + 18 = 10 B + A

or, 18=nine(B-A), giving B-A=2

As in step with the question, A=twice the distinction between A and B

Hence A=2*2=4

B=2+4=6

The original number is forty + 6 = 46.

Question 33. 1st three Letters Are Denoted By Its Next In The Alphabet And The Next three Letters Are Denoted By Its Previous In The Alphabets A Monkey Starts Climbing Up A Tree 20ft. Tall. Each Hour, It Hops 3ft. And Slips Back 2ft. How Much Time Would It Take The Monkey To Reach The Top?

Answer :

The first hour, the monkey is going three toes up, and slips lower back 2 feet.

Zero.1..2..3..Four..Five..6

that is going up instead of horizontal.)

So the monkey is three ft - 2 ft = 1 toes high after one hour.

In the second hour, the monkey is going up three extra toes, and slips returned 2 toes. So he's at 1 feet + three feet - 2 ft = 2 feet.

Every hour, he gains three toes and loses 2 feet, for a total benefit of 1 toes. So after the seventeenth hour, he's at 17 feet excessive.

Now, right here's the twist: inside the 18th hour, he climbs up 3 feet. Since 17 feet + 3 toes = 20 ft, he is on the pinnacle of the tree!

So, it takes him 18 hours.

Question 35. A Certain Type Of Mixture Is Prepared By Mixing Brand A At Rs.Nine A Kg. With Brand B At Rs.4 A Kg. If The Mixture Is Worth Rs.7 A Kg., How Many Kgs. Brand A Are Needed To Make 40kgs. Of The Mixture?

Answer :

A + B = 40.

And at Rs 7 a kg for 40 kg, you need a total of Rs.280.

So the second equation is 9A + 4B = 280

From the first equation: B = 40 - A

and sub into the second one equation:

9A + 4(40-A) = 280

9A + 160 - 4A = 280

5A = a hundred and twenty

A = 24.

Your solution, of path, is A = 24.

Question 40. The Minute Hand Of A Clock Overtakes The Hour Hand At Intervals Of sixty four Minutes Of Correct Time. How Much A Day Does The Clock Gain Or Lose?

Answer :

Simple clarification by using Juned:

The minute hand overtakes hours hand 11 instances in 12 hours

Therefore the time taken by using the minute to overtake = (12 * 60)/11

= 65.4545 mins

In this clock the minute hand is taking sixty four mins to overtake

Therefore in 12 hours it's going to overtake 720/64 = 11.25 instances

That approach 0.25 instances extra in 12 hours or zero.Five instances greater in an afternoon

Hence, the clock profits = zero.5 instances of the normal time

⇒ sixty five.4545 * zero.5 = 32.72 mins or 360/eleven mins
