Two friends decide to get together; so they start riding bikes towards each other. They plan to meet halfway. Each is riding at 6 MPH. They live 36 miles apart. One of them has a pet carrier pigeon and it starts flying the instant the friends start traveling. The pigeon flies back and forth at 18 MPH between the 2 friends until the friends meet.
How many miles does the pigeon travel

Like? Yes | No (1)

(1 year ago)

Ans: 54 miles

Let two friends are A and B, who lives 36 miles apart.
Case-I (Pigeon first flies from B towards A)
Relative speed of Pigeon and A = 18+6 = 24 mph. Time of meeting Pigeon and A=36/24=3/2 hr.
In time 3/2 hrs, distance traveled by A & B=2*6*3/2=18 miles, Remaining distance=36-18=18 miles.
Case-II (Pigeon then flies from A towards B)
Relative speed of Pigeon and B = 18+6 = 24 mph. Time of meeting Pigeon and B=18/24=3/4 hr.
In time 3/4 hrs, distance traveled by A & B=2*6*3/4=9 miles, Remaining distance=18-9=9 miles.
Case-III (Pigeon first flies from B towards A)
Relative speed of Pigeon and A = 18+6 = 24 mph. Time of meeting Pigeon and A=9/24=3/8 hr.
In time 3/8 hrs, distance traveled by A & B=2*6*3/8=9/2 miles, Remaining distance=9 - 9/2=9/2 miles.
Case-IV (Pigeon then flies from A towards B)
Relative speed of Pigeon and B = 18+6 = 24 mph. Time of meeting Pigeon and B=(9/2)/24=3/16 hr.
In time 3/16 hrs, distance traveled by A & B=2*6*3/16=9/4 miles, Remaining distance=(9/2)-(9/4)=9/4 miles.

Thus Pigeon we fly between A and B, for 3/2, 3/4, 3/8, 3/16, ..... hrs (which forms series) until both the friends meets. Therefore total distance traveled by Pigeon=18*(3/2 + 3/4 + 3/8 + 3/16 + ......)=18*3*(~1)=54 miles.

Reply Like? Yes | No

Ans: Rs. 1992

Let CP=Rs. x, then Profit when SP is 1840 = (112.5/100)*Loss when SP is 1500
(1840-x) = (112.5/100)*(x-1500)
184000 - 100x = 112.5x - 168750
Solving, we get x = 1660
So, SP when profit is 20% = 1660*(120/100) = 1992 Rs.

Ans: 138

For A.P. series, here n=43, S=2967. If First term=a, Difference=d, then sum of an A.P. series S=(n/2)[2a + (n-1)d]
2967 = (43/2)(2a + 42d)
69 = a + 21d ---- (i)
Sum of 11th term and 33rd term = (a + 10d) + (a + 32d) = 2a + 42d = 2 x (a + 21d) = 2 x 69 = 138

New Public School has a circular layout. The school has teachers specializing in various subjects. All

classrooms of the school are equally spaced apart and located along its perimeter. Each teacher needs

to take 4 classes in a day. There is a strange rule. The first and last class has to be in the same class

roun. The other two classes have to be at two other distinct class rooms.

Ram is a math teacher. He never teaches two successive classes at two adjacent classrooms. How many distinct trips to class rooms are possible for Ram if there are 9 class rooms in the school?

In a day
First & last room should be same
Let's choose it arbitrarily, next class can be chosen in 6 ways
Because same room cannot be chosen & neighboring rooms are also not allowed
Round represntations of class: 1 2 3 4 5 6 7 8 9. 1....

Let first one be 1
Then second can be 3 4 5 6 7 8
For 3, third class can be any of 5 6 7 8
For 4, third class can be any of 2 6 7 8 9
For 5, third class can be any of 2 3 7 8 9
For 6, third class can be any of 2 3 4 8 9
For 7, third class can be any of 2 3 4 5 9
For 8, third class can be any of 2 3 4 5 6
For 9, third class can be any of 2 3 4 5 6 7
And fourth class will be again 1

So total possible classes keeping first class constant is: (4)+(5*5)+(6) = 35

Similarly first class can be changed in 9 ways => Total possible trips per day = 9*35 = 315

Please check puzzle dated 14.06.2021

If the capacity of a cylindrical tank is 4004 m^3 and the diameter of its base is 14 m, then find the depth of the tank?

Solution given is
Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/14)
h = 91 m.

I think admin has considered 2r =14 only in place of r^2 ( 7^2).

It should be

Let the depth of the tank be h meter
πr²h = 4004
h = 4004/ πr²
h = (4004 x 7/22 x 1/49)
h = 26 m.

For 12 candies, when SP=Rs 12, Loss is Rs 2.4 , So CP=12+2.4=Rs 14.4
Hence Gain, when he sells 12 candies for Rs 16 = SP - CP = 16 - 14.4 =Rs 1.6

Let men,Women are =x,y respectively
Then children are =(20-x-y)
Then amount=
3x+2y+(20-x-y)/2=20
6x+4y-x-y=20
5x+3y=20
For the Natural Numbers N (x,y)=(1,5)
So men =1
Women =5
Children =14
Expenditure=1*3+5*2+14*0.5=20

A train passes a standing man 11.3 seconds and passes a bridge of length 396m in 18 seconds .the speed of the train is

Reply Like? Yes (1) | No

(3 years ago)

Let the speed of the train be x m/sec and length of the train be y m, then y/x=11.3 or y - 11.3x = 0 --(i)
Also, (y + Length of platform)/x=18
(y+396)/x=18 => 18x-y=396 ---(ii)
Solving (i) & (ii), we get, x=59.10 and y=667.88
Hence speed of the train is 59.10 m/s

the average number of people visitedredfort on every day is 2240.but 2200 on every saturday, 3000 on sunday and on wednesday it is 1500people visited . what is the average number of people visited on remaining days in the ,month of december when there are 4 thursdays abd 4 mondays in the month?

Reply Like? Yes | No

(3 years ago)

Average Visited in December = 2240
Then total visitors = 2240*31 = 69440
As there are 4 Thursdays and 4 Mondays the other 3 are Sunday,Friday and Saturday. It means 5 Sundays 5 Fridays and 5 Saturdays
It means 5*2240+5*2200+5*3000=11200+11000+15000=37200
Remaining=69440-37200=32240
Average of remaining=32240/16=2015
So Average =2015

A man sets out by cycle from Delhi to Rohtak, and at the same time another man starts from Rohtak by cycle to Delhi. After passing each other they complete their journeys in 3 1/3and 4 4/5 hours respectively. At what rates does the second

Let A and B are the persons.
A travelled x km,B travelled y km before they meet.
Time taken for A and B to reach their destinations are 10/3h,24/5h
Speeds are y/(10/3),x/(24/5)
At the time they meet they travelled same time => x/(3y/10)=y/5x/24)
10x/3y = 24y/5x=>50x^2=72y^2
=>x^2/y^2=72/50
x/y=√(1.44)=1.2
=>x=1.2y
Total distance =(x+y)=(x+x/1.2)=2.2x/1.2=11x/6
Now time taken for B=(11x/6)/(5x/24)
=11*24/6*5=44/5=8h 48m

If the sum of the first 43 terms of an arithmetic progression is 2967, then find the sum of the 11th and the 33rd terms of the same series.

Reply Like? Yes | No

(3 years ago)

First term = a, Number of terms=n, Difference = d
nth term = a+(n-1)d
11th term = a+10d, 33rd term = a+32d
Sum of 11th & 33rd= 2a+42d = 2(a+21d)=2(22nd term)

Middle term = Total sum/n
43/2 th term = 22nd term = 2967/43 = 69

=>Sum of 11th & 33rd = 2(69) = 138

Sum of first 43 terms in A.P=43(2a+42d)/2=2967
11th term +33rd terms =(a+10d)+(a+32d)=(2a+42d)
43(2a+42d)/2=2967=>(2a+42d)=2967*2/43=138
