w
u
t
l
Explanation:
Difference of 3 is in between two alphabets
i + 3 = m (j,k,l)
m + 3 = q (n,o,p)
q + 3 = u (r,s,t)
u is the answer.

Explanation:
Anns brother is Neil John (1 x 3=3).
Mary s brother Sam paul ( 2 x 4=8).
Roses brother John Brown (3 x 1=3).
Lisas Brother is Tim Smith (4 x 2 = 8).
1 + 2 + 3 + 4 + 3 + 8 + 3 + 8 = 32
Anns brother is Neil John (1 x 3=3).
Mary s brother Sam paul ( 2 x 4=8).
Roses brother John Brown (3 x 1=3).
Lisas Brother is Tim Smith (4 x 2 = 8).
1 + 2 + 3 + 4 + 3 + 8 + 3 + 8 = 32
34754.Joe`s age, Joe`s sister`s age and Joe`s fathers age sums up to a century. When son is as old as his
father, Joe`s sister will be twice as old as now. When Joe is as old as his father then his father is twice as old as when his sister was as old as her father.Age of her father ?
father, Joe`s sister will be twice as old as now. When Joe is as old as his father then his father is twice as old as when his sister was as old as her father.Age of her father ?
60
50
65
55
Explanation:
Joe + sister + father = 100
After x years let us consider Joe`s age is equal to his father
Joe + x = father
Therefore,
sister + x = 2 x sister
$\Rightarrow$ sister = x
Joe + sister = father
Therefore,
2 $\times$ father = 100
Hence, Father = 50
Joe + sister + father = 100
After x years let us consider Joe`s age is equal to his father
Joe + x = father
Therefore,
sister + x = 2 x sister
$\Rightarrow$ sister = x
Joe + sister = father
Therefore,
2 $\times$ father = 100
Hence, Father = 50
34755.X Z Y + X Y Z = Y Z X.
X = 5, Y = 4, Z = 9
X = 9, Y = 5, Z = 4
X = 5, Y = 9, Z = 4
X = 4, Y = 9, Z = 5
Explanation:
Find the three digits
2nd column, Z + Y = Z shows a carry so, Z + Y + 1 = 10 + Z
$\Rightarrow$ Y = 9
1st column, X + X + 1 = 9
$\Rightarrow$ X = 4 so, Z = 5
459 + 495 = 954
X = 4, Y = 9, Z = 5

34756.An escalator is descending at constant speed. A walks down and takes 50 steps to reach the bottom. B runs down and takes 90 steps in the same time as A takes 10 steps. How many steps are visible when the escalator is not operating?
100
200
300
150
Explanation:
Lets suppose that A walks down 1 step / min and
escalator moves n steps/ min
It is given that A takes 50 steps to reach the bottom
In the same time escalator would have covered 50n steps
So total steps on escalator is 50 + 50n.
Again it is given that B takes 90 steps to reach the bottom and time
taken by him for this is equal to time taken by A to cover 10 steps
i.e 10 minutes. So in this 10 min escalator would have covered 10n steps.
So total steps on escalatro is 90 + 10n
Again equating 50 + 50n = 90 + 10n we get n = 1
Hence total number of steps on escalator is 100.

34757.There are 8 digits and 5 alphabets.In how many ways can you form an alphanumeric word using 3 digits and 2 alphabets?
43500
43200
54300
43100
Explanation:
Select 3 digits from 8 digits i. e.
8C3 ways
And also select 2 alphabets from 5 alphabets i.e.,
5C2 ways
Now to form a alphanumeric word of 5 characters we have to arrange the 5 selected digits.
So the answer is .
8C3 $\times$ 5C2 $\times$ 5! = 43200

34758.In an Octagon the number of possible diagonals are?
60
40
30
20
Explanation:
Formula : Number of diagonals for n sided regular polygon = $^nC_{2}$ - n
For Octagon n = 8
Number of diagonals = $^8C_{2}$ - 8 = 20
Formula : Number of diagonals for n sided regular polygon = $^nC_{2}$ - n
For Octagon n = 8
Number of diagonals = $^8C_{2}$ - 8 = 20

163
144
121
155
Explanation:
In that sequence first number is 7
7 + 7 =14
14 + 41 = 55
55 + 55 = 110
110 + 011 =121
Next number in that sequence = 121
In that sequence first number is 7
7 + 7 =14
14 + 41 = 55
55 + 55 = 110
110 + 011 =121
Next number in that sequence = 121
