If January 1, 1996, was Monday, what day of the week was January 1, 1997?
The year 1996 is divisible by 4, so it is a leap year with 2 odd days. As per the question, the first day of the year 1996 was Monday, so the first day of the year 1997 must be two days after Monday. So, it was Wednesday.
How many times do the hands of a clock coincide in a day?
The hands of a clock coincide only once between 11 O' clock and 1 O' clock, so in every 12 hours, the hands of a clock will coincide for 11 times.
∴ In a day or 24 hours, the hands of a clock will coincide for 22 (11+11) times.

A mother is twice as old as her son. If 20 years ago, the age of the mother was 10 times the age of the son, what is the present age of the mother?
Let the age of son = X years
∴Age of mother would be =2X
As per question 20 years ago;
10 (X -20) = 2X - 20
10X - 200 = 2X - 20
10X - 2X= - 20 + 200
8X = 180
X = 180/8 = 22.5 years
∴ Age of mother = 22.5 * 2 = 45 years
A man got Rs. 130 less, as simple interest, when he invested Rs. 2000 for 4 years as compared to investing Rs. 2250 for the same duration. What is the rate of interest?
Let Simple Interest be S
∴ S2 - S1 = Rs. 130
The second number is one more than twice the first,
2 x 2 +1 = 5
The third number is one less than twice the second,
5 x 2 -1 = 9
The fourth number is one more than twice the third,
9 x 2 +1 = 19
The fifth number is one less than twice the fourth.
19 x 2 - 1 = 37
Therefore, the sixth number is one more than twice the fifth. So, the missing number:
37 x 2 + 1 = 75.
The tickets numbered from 1 to 20 are mixed up and then a ticket is drawn randomly. What is the probability that the ticket has a number which is a multiple of 3 or 5?
The sample space, S= (1, 2, 3, 4, 5 ...18, 19, 20) or n(S) = 20
The event "E" of getting a multiple of 3 or 5 = (3, 6, 9, 12, 15, 18, 5, 10, 20) or n (E) = 9
So, the probability of getting multiple of 3 or 5, P (E)
A is formed by reversing the digits of B. B is 45 less than A. The sum of the digits of B is 9. What is A?
Let’s solve this bv trial and error
A and B have same digits so both have sum of digits =9
All options have sum of digits as 9
Option 1 → Reverse 36. We get 63 36+45 * 63
Option 2 → Reverse 81. We get 18 18+45*81
Option 3 → Reverse 54. We get 45 45+45 * 54
Option 4 → No need to calculate. Directly mark this as other 3 are wrong.
But if you wish you can confirm.
Reverse 72. We get 27
27+45 = 72
Manoj wants to paste the wallpaper on the wall of his room. The wall is 4 meters and 50 cm in length and 3 meters and 50 cm in height. But the wall should be covered completely only by square pieces of wallpaper having the same size. What is the number of maximum-sized wallpaper squares needed to cover the walls completely?
Wall can be covered only by using square sized wallpaper pieces.
Different sized squares are not allowed.
Length = 4 m 50 cm = 450 c m ; Height = 3 m 50 cm = 350 cm
Maximum square size of possible means HCF of 350 and 450
We can see that 350 and 450 can be divided by 50.
On dividing by 50, we get 7 and 9.
Since we cannot divide further, HCF = 50 = size of side of square
A 60-liter mixture of milk and water contains 10% water. How much water must be added to make water 20% in the mixture?
The mixture has 10% water, so the milk would be 90% of 60 liters.
Milk = 90/100 * 60 = 54 liters
∴Water = 60 ? 54 = 6 liters
Let water to be added = x liters
Now, 6+x / 60 + x * 100 = 20
6+x / 60 + x = 1/5
30 + 5x = 60+x
30 - 60 = x ? 5x
- 30 = - 4x
x =30/4 =7.5 liters
In the question below is given a statement followed by two assumptions numbered I and II. You have to consider the statement and the following assumptions and decide which of the assumptions is implicit in the statement.
Statement: If you are an engineer, we have a challenging job for you.
Assumptions:
I. We need an engineer.
II. You are an engineer.
Clearly, job is offered to an engineer. This means that he is needed. So, I is implicit. The word 'If' in the statement makes II not implicit.

Solve the following question and choose the correct alternative from the following.
- 1, 2, 3, 4, and 5 are sitting in row but not necessarily in that order.
- All of them are sitting in a row with their backs toward North
- 3 is immediate right to 5 and 4 is immediate left to 1. Only 2 is between 1 and 5.
Which of the following are at the extreme ends?
Since they have their back towards north i.e. they are facing south.
So, the left and right should be taken into consideration accordingly.
If a person is facing South, then, “Person’s Left” will be “Your Right” and vice-versa.
3 is immediate right to 5 i.e. 3, 5
4 is immediately left to 1 i.e. 1, 4
Since, 2 is between 1 and 5, so the sequence becomes
3, 5, 2, 1, 4
Thus, 3 and 4 are at extreme ends.
I. All the colleges in the city had to keep closed for three days a week.

A school has four sections A, B, C, D of Class IX students.
How many students are there in Class IX in the school?
Since the classification of the students on the basis of their results and sections form independent groups, so the total number of students in the class:
