Question 6 of 20
6. Question
Two trains of equal lengths are running on parallel tracks of same directions at the rate of 85 km/hr and 49 km/hr respectively. The faster train crosses the slower train in 15 sec. Find the length of each train?
Correct
Answer b
Let the train length be x,
Relative speed = 85 – 49 = 36 km/hr = 36*(5/18) m/s = 10 m/s
2x/10 = 15
2x = 150
X = 75 m
Length of each train = 75 m
Incorrect
Answer b
Let the train length be x,
Relative speed = 85 – 49 = 36 km/hr = 36*(5/18) m/s = 10 m/s
2x/10 = 15
2x = 150
X = 75 m
Length of each train = 75 m
Question 7 of 20
7. Question
In an examination 75% of the candidates passed in History and 60% passed in Geography and 19 % students failed in both the subjects. If 972 students passed in both the subjects, then how many candidates appeared for the examination?
Correct
Answer b
Total failed candidates= 25x+40X-19x= 46x
Passed in both subjects= 100x – 46x= 54x
Total number of appeared candidate= 100x
54x= 972
X = 18
So, Total no of appeared candidates = 18*100 = 1800
Incorrect
Answer b
Total failed candidates= 25x+40X-19x= 46x
Passed in both subjects= 100x – 46x= 54x
Total number of appeared candidate= 100x
54x= 972
X = 18
So, Total no of appeared candidates = 18*100 = 1800
Question 8 of 20
8. Question
A, B, C started a work together for Rs 665. A and B is 13/19 of the total work, while B and C did 11/19 of the whole work. What is the wage of least efficient person?
Correct
Answer d
(A+B)’s work= 13/19
(B+C)’s work= 11/19
Now, (A+B+B+C) – (A+B+C)= B
13/19+11/19-1=B
B= 5/19
A= 8/19
C= 6/19
So, Ratio of distribution= 8:5:6
Now, since B is the least efficient person
B’s share= 5/19*665= Rs 175
Incorrect
Answer d
(A+B)’s work= 13/19
(B+C)’s work= 11/19
Now, (A+B+B+C) – (A+B+C)= B
13/19+11/19-1=B
B= 5/19
A= 8/19
C= 6/19
So, Ratio of distribution= 8:5:6
Now, since B is the least efficient person
B’s share= 5/19*665= Rs 175
Question 9 of 20
9. Question
Chitra got married 9 years ago. Today her age is 1(1/3) times of that at the time of her marriage. At present, her daughter’s age is one sixth of her age. What will be her daughter’s age after three years?
Correct
Answer c
Let the age of Chitra be x years
9 years ago, age of Chitra was (x-9) years
So,
x= 1(1/3)* (x-9)
x= (4/3)*(x-9)
3x= 4x-36
X= 36
Present age of her daughter=1/6* 36= 6 years
After 3 years daughter age = 6 + 3 = 9 years
Incorrect
Answer c
Let the age of Chitra be x years
9 years ago, age of Chitra was (x-9) years
So,
x= 1(1/3)* (x-9)
x= (4/3)*(x-9)
3x= 4x-36
X= 36
Present age of her daughter=1/6* 36= 6 years
After 3 years daughter age = 6 + 3 = 9 years
Question 10 of 20
10. Question
The average salary of A, B, C is Rs 18000 per month and that of B, C, D is Rs 24000 per month. If the salary of D is thrice that of A, then the average salary of B and C is?
Correct
Answer a
Total salary of A+B+C= 18000*3……….. (i)
Total salary of B+C+D= 24000*3…….. (ii)
On subtracting both the equation we get,
D-A= 6000*3= 18000
Also D= 3A
So, 3A- A = 18000
A= 9000
So,
Average salary of B and C= (54000-9000)/2= Rs 22500
Incorrect
Answer a
Total salary of A+B+C= 18000*3……….. (i)
Total salary of B+C+D= 24000*3…….. (ii)
On subtracting both the equation we get,
D-A= 6000*3= 18000
Also D= 3A
So, 3A- A = 18000
A= 9000

Answer b
Let the train length be x,
Relative speed = 85 – 49 = 36 km/hr = 36*(5/18) m/s = 10 m/s
2x/10 = 15
2x = 150
X = 75 m
Length of each train = 75 m
Answer b
Total failed candidates= 25x+40X-19x= 46x
Passed in both subjects= 100x – 46x= 54x
Total number of appeared candidate= 100x
54x= 972
X = 18
So, Total no of appeared candidates = 18*100 = 1800
Answer d
(A+B)’s work= 13/19
(B+C)’s work= 11/19
Now, (A+B+B+C) – (A+B+C)= B
13/19+11/19-1=B
B= 5/19
A= 8/19
C= 6/19
So, Ratio of distribution= 8:5:6
Now, since B is the least efficient person
B’s share= 5/19*665= Rs 175
Answer c
Let the age of Chitra be x years
9 years ago, age of Chitra was (x-9) years

Also D= 3A
So, 3A- A = 18000
A= 9000
So,
