In railway station,Hari has to catch the train so he chooses the escalator instead of cross the track to reach the top. The escalator is moving at the constant speed, if he takes 25 steps he would reach the top in 9 seconds. If he takes 7 steps he would reach in 15 seconds. Find the total number of steps in the escalator.?
Here Assume the escalator have n steps
Now, Hari covers n - 25 steps in 9 seconds and n - 7 steps in 15 seconds.
Given that the speed in either case is same.
Then we would have (n - 25)/9 = (n - 7)/15
(n - 25)/3 = (n - 7)/5
5n - 3n = 125 - 21 = 104.
n = 104/2
n = 52 steps

In Children School,Seven different play kits are distributed among Three children how many different ways are possible?
In a consultant office 4:6 is the ratio of number of female employees and male employees.If 50% of female and 40% of male are post-graduate holders then the percentage of the candidates who are under-graduate holders is:?
Given ratio of females and males = 4:6 = 2:3
assume males = 3x and females = 2x.
Number of females who are Under-graduate holders = (100 - 50)% of 2x = 50% of 2x
Number of males who are under-graduate holders = (100 - 40)% of 2x = 60% of 3x.
Total under-graduate holders = 50% of 2x + 60% of 3x.
= x + 9x/5 = 14x/5
Required percentage = [(14x/5) / 5x] * 100 = 14x/5 * 1/5x * 100 = 14 * 4 = 56%.
Square of two more than a two digit number is multiplied and divided by 2 and 5 respectively. If twice of the result is equal to 500 then find the number?
Assume the number is x
Two more than x = x + 2
Square of the number = (x + 2)2
Multiplied and divided by 2 and 5 = 2(x + 2)2 / 5
Twice the result is 500 = 2 x 2/5 * (x + 2)2
4/5 * (x + 2)2 = 500
(x + 2)2 = 500 x 5/4
(x + 2)2 = 625
x+ 2 = 25
x = 23
Two-Third of two digit number is equal to a number whose ten's place is three less than the ten's place of the two digit number and unit's place is one more than the unit's place of the two digit number.Then find the quotient when the square of the two digit number is divided by 261.
Let the two digit number be 10x + y
2/3 of the number = 2/3 (10x + y)
Given that, 2/3 of (10x + y) = (x - 3)10 + (y + 1)
(2/3)(10x + y) = (x - 3)10 + (y + 1)
2(10x + y) = 3((x - 3)10 + (y + 1))
20x + 2y = 3(10x - 30 + y + 1)
20x + 2y = 30x - 90 + 3y + 3
-10x = y - 87
Or, 87 = 10x + y
Hence the two digit number be 87.
Square of the number divided by 261 = 87 x 87 / 261 = 29

Here the people are sitting clock wise like A,F,C,E,B,D, So according to above the two neighbours of B are D and E
If D is adjacent to F then who is adjacent to C?
E and B
D and A
D and B
Either 1 or 3
if D is Adjecent to F then adjecent of C is E and B OR D and A
Complete the sequence A, E ,I ,M ,Q ,U , _ , _
Here Each letter is come by next 3 letters
If S is ranked sixth and Q is ranked fifth, which of the following can be true?
V is ranked first or fourth
R is ranked second or third
P is ranked second or fifth
U is ranked third or fourth
If R gets more, V should be ranked not lower than:
V should not be lower than fifth because here V>P>Q and if R is highest then T is least
If R is ranked second and Q is ranked fifth, which of the following must be true?
S is ranked third
T is ranked sixth
P is ranked sixth
V is ranked fourth
R is Ranked sixth and Q is ranked fifth then according to Question V>P>Q so T is ranked sixth
If S is ranked second, which of the following can be true?
U gets more than V
V gets more than S
P gets more than R
P gets more than V
If S is ranked second then U gets more than V
If V is ranked fifth, which of the following must be true?
S scores hightest Q
R is ranked second
T is ranked third S
Q is ranked fourth
V ranked fifth then S scores highest Than Q
