1. What is the average of first five multiples of 12?

A. 36 B. 38 C. 40 D. 42

Answer: Option A
Explanation: 12*(1+2+3+4+5)[latex]\frac{1}{5}[/latex]
= 12 ∗ 15*[latex]\frac{1}{5}[/latex]
= 12 ∗ 3= 36
2. What is the difference in the place value of 5 in the numeral 754853?

A. 49500 B. 49950 C. 45000 D. 49940

Answer: Option B
Explanation: The digit 5 has two place values in the numeral, 5 * [latex]{10}^{5}[/latex] = 50,000 and 5 * [latex]{10}^{1}[/latex] = 50.
∴Required difference = 50000 - 50 = 49950
3. 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?

A. 38 years B. 40 years C. years D. 45 years

Answer: Option D
Explanation: 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 = [latex]\frac{1}{8}[/latex]
= 22.5 years
∴Age of mother = 22.5 * 2 = 45 years
4. A running man crosses a bridge of length 500 meters in 4 minutes. At what speed he is running?

A. 8.5 km/s B. 7.5 km/s C. 9.5 km/s D. 6.5 km/s

Answer: Option B
Explanation: Speed = [latex]\frac{Distance}{Time}[/latex]
Distance = 500 meters
Time = 4 minutes ⟶ 4 x 60 = 240 seconds
We need answer in km/hr:
Speed in km/hr=[latex]\frac{25}{12}[/latex]*[latex]\frac{18}{5}[/latex]=[latex]\frac{90}{12}[/latex]⟶[latex]\frac{30}{4}[/latex]= 7.5 km/s
5. In what ways the letters of the word "RUMOUR" can be arranged?

A. 180 B. 150 C. 200 D. 230

Answer: Option D
Explanation: The word RUMOUR consists of 6 words in which R and U are repeated twice.
Therefore, the required number of permutations = [latex]\frac{6!}{(2!)(2!)}[/latex]
Hence, 180 words can be formed by arranging the word RUMOUR.

Directions for Questions (1 – 5): The following table shows number of students who applied for the various posts for RRB India having different qualifications. Study the table carefully and answer the questions that follow.
In table some data are missing. Find the missing data first if it is required in any question and then proceed.

No. of students having different qualifications is independent from each-other Don’t treat any student may have more than one qualification unless it is not mentioned in questions.
Q1. If only 10th pass students are eligible for group-D exam then total number of students who applied for group-D exam from Bihar is what percent of total number of students who have qualification of degree from MP and Jharkhand together? It is given that total number of students from Bihar who applied for various posts in RRB is 95,500.

A. 13[latex] \frac{12} {13}[/latex]% B. 26[latex] \frac{12} {13}[/latex]% C. 24[latex] \frac{12} {13}[/latex]% D. 22[latex] \frac{12} {13}[/latex]% E. 23%

Answer: Option B
Explanation:
No. of students from Bihar having 10th qualification
= 95,500 – (12,500 + 16,400 + 24,000 + 32,100) = 10,500
∴ Required percentage
= [latex] \frac{10,500} {24,600 + 14,400}[/latex] x 100
= [latex] \frac{10,500} {390}[/latex]
= [latex] \frac{350} {13}[/latex]
= 26[latex] \frac{12} {13}[/latex]%
Q2. If only degree holders are eligible for ALP post then find the average number of students who have applied for ALP post from all the states together.

A. 26,750 B. 28,450 C. 27,850 D. 28,750 E. 27,580

Answer: Option D
Explanation:
Required average number of students
= [latex] \frac{1} {6}[/latex] x (32,100 + 72,500 + 24,600 + 16,500 + 14,400 + 12,400)
= [latex] \frac{1} {6}[/latex] x 1,72,500
= 28,750
Q3. According to RRB, only those candidates who have qualification of both ITI & higher qualification can apply for the post of Technician then find the total number of students who has applied for the post of Technician from all the states together. It is given that the number of students who have (ITI + Diploma) qualification from Assam is 45% of number of students from Bihar having same qualifications as that of students from Assam.

A. 90,400 B. 87,500 C. 95,400 D. Can’t be determined E. 1,30,200

Answer: Option E
Explanation:
24000 + 54600 + 16400 + 12000 + 12400 + 45% of 24000 = 130200
Q4. If number of students having (10th + ITI) qualification from MP is 25% more than that from Assam having same qualification then total number of students having (10th + ITI) from these two states is what percent of total number of students having (10th + ITI) from all the six states together? It is given that total number of students from Assam having (10th + ITI) qualification is 10,000

A. 28[latex] \frac{22} {101}[/latex]% B. 22[latex] \frac{28} {101}[/latex]% C. 26[latex] \frac{28} {101}[/latex]% D. 22[latex] \frac{38} {101}[/latex]% E. 28[latex] \frac{38} {101}[/latex]%

Answer: Option B
Explanation:
No. of students from MP and Assam together having (10th + ITI) qualification
10000 + [latex] \frac{5} {4}[/latex] x 10000 = 22,500
Total students from all the six states together having (10th + ITI) qualification
= 16,400 + 42,000 + 12,500 + 10,500 + 9,600 + 10,000 = 1,01,000
∴ Required percentage
= [latex] \frac{22,500} {1,01,000}[/latex] x 100
= 22[latex] \frac{28} {101}[/latex]
Q5. If total number of students having 12th qualification from UP is 100% more than that from Gujrat and Jharkhand together having same qualification, then what is the total number of students having 12th qualification from U.P. It is given that the ratio of number of students from Gujrat and Jharkhand having 12th qualification is 8 : 7 and total number of students having 12th qualification from all the states is 85,700.

A. 36,000 B. 45,000 C. 24,000 D. 54,000 E. 32,000

Answer: Option A
Explanation:
Let no. of students from Gujrat and Jharkand having 12th qualification is 8x and 7x respectively.
8x + 7x + [latex] \frac{200} {100}[/latex] × (8x + 7x) + 12,500 + 10,000 + 9,200 = 85,700
⇒ x = 1,200
∴ Required answer = 1200 × 30 = 36,000
