Directions (6 – 10): What value should come in the place of question mark (?) in the following questions?
125 % of 2580 + 85 % of 800 = 250 % of ?
Correct
Answer: d)
(125/100)*2580 + (85/100)*800 = (250/100)*x
3225 + 680 = (5x/2)
3905 = (5x/2)
3905*(2/5) = x
X = 1562
Incorrect
Answer: d)
(125/100)*2580 + (85/100)*800 = (250/100)*x
3225 + 680 = (5x/2)
3905 = (5x/2)

Question 11 of 20
11. Question
A shopkeeper earns a profit of 10% after allowing a discount of 40% on the Marked price. Find the Cost Price of the article whose marked price is 1650?
Correct
Answer: b)
Selling price = 1650*60/100 = 990
Cost price*(110/100) = 990
Cost price = (990/110)*100 = Rs. 900
Incorrect
Answer: b)
Selling price = 1650*60/100 = 990
Cost price*(110/100) = 990
Cost price = (990/110)*100 = Rs. 900
Question 12 of 20
12. Question
The sum of twice the age of Yuvaraj and his father is 107 and the sum of twice the age of his father and Yuvaraj is 136. The average age of Yuvaraj and his father and mother is 43. Then find the present age of Yuvaraj’s mother?
Correct
Answer: d)
Let the age of Yuvaraj and his father be x and y,
2x + y = 107 ->(1)
X + 2y = 136 –>(2)
By solving (1) and (2),
Y = 55, X = 26
The average age of Yuvaraj and her father and mother = 43
Sum of the ages of Yuvaraj and her father and mother = 43*3 = 129
Present age of Yuvaraj’s mother = 129 – (55 + 26) = 48 years
Incorrect
Answer: d)
Let the age of Yuvaraj and his father be x and y,
2x + y = 107 ->(1)
X + 2y = 136 –>(2)
By solving (1) and (2),
Y = 55, X = 26
The average age of Yuvaraj and her father and mother = 43
Sum of the ages of Yuvaraj and her father and mother = 43*3 = 129
Present age of Yuvaraj’s mother = 129 – (55 + 26) = 48 years
Question 13 of 20
13. Question
A tank can be filled by three pipes A, B and C in 21 hours. All the pipes were opened for 3 hours and then pipe C was closed. A and B filled the remaining tank in 24 hours. Find the time taken by pipe C alone to completely fill the tank?
Correct
Answer: a)
(A + B + C)’s one hour work = (1/21)
(A + B + C)’s 3 hour work = (3/21) = 1/7
Remaining = 6/7
(6/7)*(A + B)’s whole work = 24
(A + B)’s whole work = 24*(7/6) = 28 hours
C’s one hour work = (1/21) – (1/28) = (28 – 21)/(28*21)
= > (1/84)
C alone can complete the tank in 84 hours.
Incorrect
Answer: a)
(A + B + C)’s one hour work = (1/21)
(A + B + C)’s 3 hour work = (3/21) = 1/7
Remaining = 6/7
(6/7)*(A + B)’s whole work = 24
(A + B)’s whole work = 24*(7/6) = 28 hours
C’s one hour work = (1/21) – (1/28) = (28 – 21)/(28*21)
= > (1/84)
C alone can complete the tank in 84 hours.
Question 14 of 20
14. Question
A and B together can complete a work in 18 days, while A is 50% more efficient than B, then find in how many days the work will be complete if they work on alternative days starting with A?
Correct
Answer: c)
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) = 1/18
5x/(2x*3x) = 1/18
X = 15
The time taken by A and B = 2x, 3x = 30 and 45 days
Total units = 90 (LCM of 30, 45)
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 36 days = 5*18 = 90 units
Work will be completed in 36 days
Incorrect
Answer: c)
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) = 1/18
5x/(2x*3x) = 1/18
X = 15
The time taken by A and B = 2x, 3x = 30 and 45 days
Total units = 90 (LCM of 30, 45)
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 36 days = 5*18 = 90 units
Work will be completed in 36 days
Question 15 of 20
15. Question
A 250 m long train crosses a 135 m platform at the speed of 66 km/hr. What is the time taken by train to cross the platform?
Correct
Answer: b)
T = D/S
T = (250 + 135)/[66*(5/18)]
T = (385*18)/(66*5)
T = 21 sec
Incorrect
Answer: b)
T = D/S
T = (250 + 135)/[66*(5/18)]
T = (385*18)/(66*5)
T = 21 sec

Total number of students playing various sports in School A is 32 % of total number of students in School A. Find the total number of students not playing any games in School A?
Correct
Answer: c)
Total number of students playing various sports in School A
= > 150 + 120 + 180 + 100 + 90 = 640
(32/100)*Total students in School A = 640

The total number of students not playing any games in School A
= > 2000*(68/100) = 1360

Answer: c)
Total number of students playing various sports in School A
= > 150 + 120 + 180 + 100 + 90 = 640
(32/100)*Total students in School A = 640
Total students in School A = 640*(100/32) = 2000
