Question 1. A Boy Is Running At A Speed Of P Km/hr To Cover A Distance Of 1km But Due To The Slippery Ground, His Speed Is Reduced By Q Km/hr(p>q).If The Takes R Hours To Cover The Distance Then?

Answer :

Actual speed = (P-Q)km/hr , time taken =R hrs 

Distance =(Speed x time) 

Therefore, 1 =(P-Q)R => 1/R =(P-Q).

Question 2. Sunil Covers A Distance By Walking For 6 Hours While Returning His Speed Decreases By 1km/hr And He Takes nine Hours To Covers The Same Distance What Was His Speed In Turns Journey?

Answer :

Let the rate in go back journey be x km/hr, then 

6(x +1) =9x 

=> 3x =6 

=> x =2 

Hence the velocity in return journey is 2km/hr.

Question three. A Takes 2 Hours More Than B To Walk D Km. If A Doubles His Speed Then He Can Make It In 1 Hour Less Than B. How Much Time Does B Require For Walking D Km?

Answer :

Suppose B takes x hours to stroll d km 

Then A takes (x+2) hours to stroll d km 

With double of the speed. 

A will take ½(x+2)hours 

Therefore, x -half of(x+2) = 1 

 2x –(x+2) 

 X =four 

Hence B takes four hours to stroll d km.

Question 4. 12 Men Or 18 Women Can Reap A Field In 14 Days. The Number Of Days That eight Men And sixteen Women Will Take To Reap It?

Answer :

12 men = 18 girls or 1 guy = 3/2 ladies 

Therefore eight guys + sixteen ladies = (eight × 3/2 + 16) girls i.E.., 28 ladies 

Now 18 ladies can gain the sphere in 14 days 

Therefore, 28 women can gain it in = 9 days.

Question five. If three Men Or 4 Women Can Construct A Wall In forty three Days, Then The Number Of Days That 7 Men And five Women Take To Construct It Is?

Answer :

3 guys = 4 ladies or 1 man = 4/3 girls 

Therefore 7 guys + five ladies = (7 × four/3 + five)women i.E.., 43/three women 

4 women can assemble the wall in 43 days 

Therefore, 43/three girls can construct it in = 12 days.

Question 10. If forty% Of A Number Is Equal To Two-1/3 Of Another Number, What Is The Ratio Of First Number To The Second Number?

Answer :

Let 40% of A = 2/3 B. Then,

40A/a hundred = 2B/3 => 2A/5 = 2B/three

A/B = (2/3 * five/2) = five/three

A:B = 5:three.

Question eleven. Ratio Of The Earnings Of A And B Is four:7. If The Earnings Of A Increases By 50% And Those Of B Decreased By 25%, The New Ratio Of Their Earnings Becomes 8:7. What Are A's Earnings?

Answer :

Let the authentic earnings of A and B be Rs. 4x and Rs. 7x.

New income of A = 150% 0f Rs. 4x = (one hundred fifty/100 * 4x) = Rs. 6x

New profits of B = 75% of Rs. 7x = (seventy five/a hundred * 7x) = Rs. 21x/4

6x:21x/four = eight:7

This does no longer deliver x. So, the given data is inadequate.

Question thirteen. Rs.One thousand Is Invested At five % P.A Simple Interest If The Interest Is Added To The Principle After Every 10 Years. The Amount Will Become Rs. 2000 After?

Answer :

S. I for 10 Years = Rs (a thousand × five/one hundred × 10) = Rs 500 

Principle after 10 Years becomes = Rs (one thousand + 500) 

= Rs 1500 

S. I on it = Rs (2000 - 1500) = Rs 500 

Time = (50000/7500) Years = 6 2/three Years 

Total Time = (10 + 6 2/3) Years = 16 2/3 Years.

Question 14. The Average Of Women And Child Workers In A Factory Was 15%12 months. The Average Age Of All The 16 Children Was 8yr And Average Age Of Women Workers Was 22 Yrs If Ten Women Workers Were Married Then The Number Of Unmarried Women Workers Were?

Let the variety of ladies workers be x

According to the question 22*x+sixteen*eight = 15(sixteen+x) 

=> 22x+128 =240 +15x 

=> 22x-15x = 240 -128 

=> 7x=112 

Therefore, x=112/7 =sixteen 

Therefore, Unmarried ladies workers =(16-10) =6.

Question 15. A Person Travels From X To Y At A Speed Of 40km/h And Returns By Increasing His Speed 50%. What Is His Average Speed For Both The Trips?

Answer :

Speed of individual from x to y =40 km/h 

Speed of man or woman from y to x =(40x150)/a hundred = 60km/h

Question 17. Three Taps A, B And C Can Fill A Tank In 12, 15 And 20 Hours Respectively. If A Is Open All The Time And B And C Are Open For One Hour Each Alternately, The Tank Will Be Full Is?

Answer :

(A + B)'s 1 hour paintings = (1/12 + 1/15) = 3/20

(A + C)'s 1 hour work = (1/12 + 1/20) = 2/15

Part stuffed in 2 hrs = (three/20 + 2/15) = 17/60

Part filled in 6 hrs = three * 17/60 = 17/20

Remaining part = 1 - 17/20 = three/20

Now, it is the flip of A and B and 3/20 element is stuffed through A and B in 1 hour.

Question 20. The Difference Between Simple And Compound Interest (compounded-annually) On A Sum Of Money For 2 Years At 10% Per Annum Is Rs sixty five. The Sum Is?

Answer :

Let the sum be Rs x.

Then [x × (1 +10/100)2 - x] – (x × 10/a hundred × 2) = 65 

=> (x × eleven/10 × eleven/10 - x) – x/five = sixty five 

=> (121x/100 - x) – x/5 = sixty five 

=> (21x/100 – x/five) = sixty five 

=> (21x – 20x) = 6500 

=> X = 6500.

Question 28. Ajay And Vijay Have Some Marbles With Them. Ajay Told Vijay "if You Give Me 'x' Marbles, Both Of Us Will Have Equal Number Of Marbles". Vijay Then Told Ajay "if You Give Me Twice As Many Marbles, I Will Have 30 More Marbles Than You Would". Find 'x'?

Answer :

If Vijay gives 'x' marbles to Ajay then Vijay and Ajay would have V - x and A + x marbles.

V - x = A + x --- (1)

If Ajay gives 2x marbles to Vijay then Ajay and Vijay would have A - 2x and V + 2x marbles.

V + 2x - (A - 2x) = 30 => V - A + 4x = 30 --- (2)

From (1) we've V - A = 2x

Substituting V - A = 2x in (2)

6x = 30 => x = five.

Question 29. A Man Traveled A Total Distance Of 1800 Km. He Traveled One-0.33 Of The Whole Trip By Plane And The Distance Traveled By Train Is Three-5th Of The Distance Traveled By Bus. If He Traveled By Train, Plane And Bus, Then Find The Distance Traveled By Bus?

Question 32. There Are Two Identical Red, Two Identical Black, And Two Identical White Balls.In How Many Different Ways Can The Balls Be Placed In The Cells (each Cell To Contain One Ball) Shown Above Such That Balls Of The Same Colour Do Not Occupy Any Two Consecutive Cells?

Answer :

Case I : 2 balls of the same coloration and  balls are a specific coloration are organized. 

Two balls of the same shade and  balls of different colorings may be arranged collectively wherein  balls of the identical shade are adjacent =four!/2!X2! = 6 approaches 

Therefore, Total number of preparations = 6x3 =18 approaches

Case II : Two shades out of 3 may be selected in = 3C1 = 3ways 

Now 2 balls of every shade can be arranged rather in 2 methods 

Thus 4 balls may be arranged(two of each colorations) 

= 3x2 = 6ways 

 Hence general range of arrangements = 18+6 =24 methods.
