Q. Two merchants sell, each an article for Rs.1000. If Merchant A computes his profit on cost price, while Merchant B computes his profit on selling price, they end up making profits of 25% respectively. By how much is the profit made by Merchant B greater than that of Merchant A?
Option

Reply Like? Yes | No

(6 years ago)

Given SP = 1000
FOR A,
(SP-CP)/CP * 100 = PP
(1000-CP)/CP *100 = 25
(1000/CP - 1)*100 = 25
1000/CP - 1 = 25/100 = 0.25
1000/CP = 1.25
CP = 1000/1.25 = 800rs
Profit = SP-CP = 1000-800 = 200

FOR B,
(SP-CP)/SP = PP
(1000-CP)/1000 = 25%
1 - CP/1000 = 0.25
CP/1000 = 0.75
CP = 750
Profit = SP-CP = 1000-750 = 250rs

So, profit of B - A = 250-200 = Rs.50/-

By 50rs profile made by Merchant B is greater than that of Merchant A.

explanation: let k years ago
then (4x+k)/(3x+k)=5/3
then x=-2k/3
now present ages become -8k/3 and -2k
according to the given statement i.e, after 4 years this ratio will become 9:7
the ratio becomes
(4-(8k/3))/(4-2k)=9/7

There are 9 three digit numbers . Each number is reversed and the reversed number is subtracted from the original number. The results were found to have an average of 0.

Reply Like? Yes | No

101 is the least 3 digit number to have "hundreds digit not less than unit digit"

Result = 101-101 = 0

999 is the greatest 3 digit number.
Result = 999-999 = 0

Rest 7 numbers take any palindrome numbers like 252, 373, 444, 505, 666, 767, 868
Or any set giving average result zero like:
234, 432, 566, 775, 476, 988, 777

Reply Like? Yes | No

Let points scored in first match be x

Then, his points are:
x, x-2, x-4,..., x-14, x-16
Average = [9x- 2(1+2+3...+8)]/9
= [9x-2(8*9)/2]/9
= [9x-72]/9
= x-8 = 16...., Given
=> x = 24
So second match score = 24-2 = 22
Eight match score = x-14 = 24-14 =10
Average points = (22+10)/2
= 16

There are N students in a class.their class teacher gave them a task of finding the average of the first N natural numbers and each of them left out a different number and found the average of remaining numbers.the average of the averages obtained by all the students was 21.find N .

Reply Like? Yes (1) | No

(6 years ago)

sum of sum of numbers given by all N students = N*( 21*(N-1) )

Each student leaves 1 number,,,
let the numbers left by students be k1,k2,k3, ....,kn,,,,so for student1 it will be

21(N-1) = sum of N numbers - k1

=N(N+1)/2 - k1

for every student, it will be N(N+1)/2 - ki
Adding sum obtained by all N students , we get

N*( 21*(N-1) ) = N* ( N(N+1)/2 ) - (k1 -k2 ...... -kn)

adding k1 to kn, we get sum of N numbers

so it will be,, 21*N*(N - 1 ) = (N - 1)*N*(N+1)/2

solving it, we get N=41

an ant smartly moves across a staircase taking the shortest distance. calculate the distance it takes to reach top to B from A given that staircase consist of 2 steps. it also known that the length,breadth and height is 6cm,2cm and 1cm respectively

Reply Like? Yes (2) | No

(6 years ago)

Shortest distance would be when ant doesn't travel any distance in the direction of length while climbing the height or passing the breadth.
So for one stair the smart Ant should cover = Height of Stair+ Breadth of stair = 1+2 =3 cm

So for 2 stairs the shortest distance traveled by Ant = 2*3= 6 cm

Like? Yes (2) | No (3)

(6 years ago)

Ant will move diagonally on each step covering a distance of sqrt 5 cms.
Hence total distance travelled for two steps = 2*sqrt 5 cms.

Like? Yes (3) | No (1)

(6 years ago)

Assume there is a staircase with 2 steps length = 6cm and breadth and height are 1 and 2
so the shortest distance is from left end of the 1st step to right end of the 2nd step which forms a right angled triangle, triangle side are AB, AC and BC.
By using pythagoras theorem,
AC^2 = AB^2+BC^2
AC^2 = 6^2+(2+1+2+1)^2 [height + breath of 2 steps]
AC^2 = 36+36
AC = 6 _/ 2

Q) A positive integer is selected at random and is divided by 7,what is the probability that the
remainder is 1?
A. 3/7 B. 4/7 C. 1/7 D. 2/7

Reply Like? Yes | No

(6 years ago)

1/7
Any number N, when divided by 7, could have remainder as {0,1,2,3,4,5,6}
So total number of possible outcomes = 7
Total number of positive outcome =1

Hence 1/7

1992 Feb have 5 Sundays. In which year, the month Feb have 5 Sundays next?

Reply Like? Yes | No

(6 years ago)

2020 will have the next,

For every 4 years( between 2 leap years), there will 365*4+1 days
= 1456 days
= 1461+5 days
= 208 weeks + 5 days
= 208 negligible weekdays count + 5 to be considered odd days.

So, 1996 Feb will have 5 Fridays ( because Sunday + 5th odd day = Friday)

So, for every 4 years, if we get 5 odd days.
then to get 7 or multiple of 7 as odd day,
we should go on searching in multiples of 5(required) days,
i.e. in 5,10,15,20,25,30,35,40,45,....
35 is the nearest multiple of both 5,7 which is nothing but LCM(least common multiple)

So to get 35 odd days, we are taking 7 leap years to pass out = 7*4years = 28 years
= 1992 + 28 = 2020

You can cross check it with real calendar, both 1992 and 2020 have 5 Saturdays(respectively)

Short cut, easy, handy method is to find odd days in these kind of questions and use logic accordingly.

ramesh and suresh started journey from bangalore to chennai. ramesh starts at 1 30pm from bangaore and suresh starts 3pm at banglore and suresh over took ramesh at 6 pm and reaches at 9 pm at chennai.when will ramesh reached at chennai?

Reply Like? Yes | No

10:30 pm.

Let speed of Ramesh & Suresh be R & S respectively, then 4.5R = 3S
=> ratio of speeds = R : S = 2 : 3
So ratio of time = 3 : 2
As Suresh reached in 6 hrs, so Ramesh took 6*(3/2)=9 hrs.
Hence Ramesh will reach at (1:30pm +9 hrs) = 10:30 pm.

Suresh starts 3pm at banglore and Suresh over took Ramesh at 6 pm and reaches at 9 pm at chennai.
It means he overtook Ramesh at mid point of journey.
Ramesh completed half journey in 4.5 hrs and Suresh completed half journey in 3 hrs.
So Ramesh will complete whole journey in 9 hrs and he will reach Chennai at 10.30 PM.
