Question 11 of 20
11. Question
The perimeter of a rectangular field is thrice the perimeter of a square field. If one of the sides of the square field is 10 m and breadth of the rectangular field is 20 m, then find the area of the rectangular field?
Correct
Answer: a)
Perimeter of square field = 10*4 = 40m
Perimeter of the rectangular field = 3*40 = 120 m
Let the length of the rectangular field be x,
120 = 2*(x + 20)
120 – 40 = 2x
X = 80/2 = 40 m
Area of the rectangular field = 40*20 = 800 Sq. m
Incorrect
Answer: a)
Perimeter of square field = 10*4 = 40m
Perimeter of the rectangular field = 3*40 = 120 m
Let the length of the rectangular field be x,
120 = 2*(x + 20)
120 – 40 = 2x
X = 80/2 = 40 m
Area of the rectangular field = 40*20 = 800 Sq. m
Question 12 of 20
12. Question

A and B together can complete a work in 24 days, while A is 150% efficient of B, then find in how many days the work will be complete if they work on alternative days starting with A?
Correct
Answer: b)
Efficiency of A and B = 150: 100 = 3: 2
The ratio of time taken by A and B = 2: 3 (2x, 3x)
(1/2x) + (1/3x) = 1/24
5x/(2x*3x) = 1/24
X = 20
The time taken by A and B = 2x, 3x = 40 and 60 days
Total units = 120 (LCM of 40, 60)
A’s one day work = 3 units
B’s one day work = 2 units
Work done in 2 days = 3 + 2 = 5 units
Work done in 24 days = 5*24 = 120 units
Work will be completed in 48 days
Incorrect
Answer: b)
Efficiency of A and B = 150: 100 = 3: 2
The ratio of time taken by A and B = 2: 3 (2x, 3x)
(1/2x) + (1/3x) = 1/24
5x/(2x*3x) = 1/24
X = 20
The time taken by A and B = 2x, 3x = 40 and 60 days
Total units = 120 (LCM of 40, 60)
A’s one day work = 3 units
B’s one day work = 2 units
Work done in 2 days = 3 + 2 = 5 units
Work done in 24 days = 5*24 = 120 units
Work will be completed in 48 days
Question 14 of 20
14. Question
Difference between Simple interest and Compound interest on a certain sum at the rate of 12% per annum for two years is Rs. 432. Find the compound interest on that sum at the rate of 5% per annum after 2 years?
Correct
Answer: d)
The difference between CI and SI for two years is,
Diff = P*(r/100)^{2}
=> 432 = P*(12/100)^{2}
=> 432 = P*(3/25)^{2}
=> 432 = P*(9/625)
=> P = Rs. 30000
Compound Interest:
30000*(5/100) = 1500
31500*(5/100) = 1575
C.I = 1500 + 1575 = Rs. 3075
Incorrect
Answer: d)
The difference between CI and SI for two years is,
Diff = P*(r/100)^{2}
=> 432 = P*(12/100)^{2}
=> 432 = P*(3/25)^{2}
=> 432 = P*(9/625)
=> P = Rs. 30000
Compound Interest:
30000*(5/100) = 1500
31500*(5/100) = 1575
C.I = 1500 + 1575 = Rs. 3075
Question 15 of 20
15. Question
Train A crosses a pole in 40 seconds and Train B crosses the same pole in one minute. The length of Train A is half the length of Train B. What is the ratio of the speed of Train A to that of Train B?
Correct
Answer: a)
The length of Train A = (1/2)* the length of Train B
The length of Train A : The length of Train B = 1 : 2 (x, 2x)
Speed of Train A = x/40
Speed of Train B = 2x/60 = x/30
Required ratio = (x/40): (x/30) = 3: 4
Incorrect
Answer: a)
The length of Train A = (1/2)* the length of Train B
The length of Train A : The length of Train B = 1 : 2 (x, 2x)
Speed of Train A = x/40
Speed of Train B = 2x/60 = x/30
Required ratio = (x/40): (x/30) = 3: 4
Question 16 of 20
16. Question
Directions (Q. 16 – 20) Study the following information carefully and answer the given questions:
Following pie chart1 shows the percentage distribution of total number of employees in 6 different departments in a certain city and pie chart2 shows the percentage distribution of total number of male employees among them.
Total number of female employees working in Production department is what percentage of total number of male employees working in Accounts department?
Correct
Answer: c)
Total number of female employees working in Production department
= > [7200*(24/100) – 4000*(18/100)]
= > 1728 – 720 = 1008
Total number of male employees working in Accounts department
= > 4000*(16/100) = 640
Required % = (1008/640)*100 = 157.5 %
Incorrect
Answer: c)
Total number of female employees working in Production department
= > [7200*(24/100) – 4000*(18/100)]
= > 1728 – 720 = 1008
Total number of male employees working in Accounts department
= > 4000*(16/100) = 640
Required % = (1008/640)*100 = 157.5 %
