Directions (6 – 10): What value should come in the place of question mark (?) in the following questions?
15 % of ? – 2366 ÷ 13 – 1275 ÷ 3 = 68
Correct
Answer: c)
(15/100)*x – (2366/13) – (1275/3) = 68
(3x/20) = 68 + 182 + 425
(3x/20) = 675
X = 675*(20/3) = 4500
Incorrect
Answer: c)
(15/100)*x – (2366/13) – (1275/3) = 68
(3x/20) = 68 + 182 + 425
(3x/20) = 675

Question 11 of 20
11. Question
The angles of quadrilateral are in the ratio of 3: 4: 5: 6. The highest angle of quadrilateral is 2 times of the smallest angle of parallelogram. Find the adjacent angles of parallelogram? (In degree)
Correct
Answer: d)
Total angles of quadrilateral = 360^{0}
18’s = 360^{0}
1’s = 20^{0}
Highest angle of quadrilateral = 6’s = 120^{0}
Smallest angle of parallelogram = 120^{0}/2 = 60^{0}
Sum of the adjacent angles of parallelogram = 180^{0}
Adjacent angle of parallelogram = 180^{0} – 60^{0} = 120^{0}
Incorrect
Answer: d)
Total angles of quadrilateral = 360^{0}
18’s = 360^{0}
1’s = 20^{0}
Highest angle of quadrilateral = 6’s = 120^{0}
Smallest angle of parallelogram = 120^{0}/2 = 60^{0}
Sum of the adjacent angles of parallelogram = 180^{0}
Adjacent angle of parallelogram = 180^{0} – 60^{0} = 120^{0}
Question 12 of 20
12. Question
A, B and C’s profit ratio will be 4: 5: 3 and the period of investment in the ratio of 3: 2: 1. Find the investment ratio?
Correct
Answer: a)
Investment * Period = Ratio of profit
A, B and C’s profit ratio = 4: 5: 3
Period = 3: 2: 1
Investment ratio = Ratio of profit / Period
= > (4/3): (5/2): (3/1)
= > 8: 15: 18
Incorrect
Answer: a)
Investment * Period = Ratio of profit
A, B and C’s profit ratio = 4: 5: 3
Period = 3: 2: 1
Investment ratio = Ratio of profit / Period
= > (4/3): (5/2): (3/1)
= > 8: 15: 18
Question 13 of 20
13. Question
Two trains A and B of same length running in same direction with a speed of 54 km/hr and 72 km/hr respectively can cross each other in how many seconds if train A crosses a standing man in 15 seconds?
Correct
Answer: b)
Speed of train A in m/s = 54*5/18 = 15 m/s
Length of train A= 15 *15 = 225 m
Speed of train B in m/s = 72*5/18= 20 m/s
Time required to cross each other
T = D/S
T = (225 + 225)/(20 – 15)
T = 450/5
T = 90 seconds
Incorrect
Answer: b)
Speed of train A in m/s = 54*5/18 = 15 m/s
Length of train A= 15 *15 = 225 m
Speed of train B in m/s = 72*5/18= 20 m/s
Time required to cross each other
T = D/S
T = (225 + 225)/(20 – 15)
T = 450/5
T = 90 seconds
Question 14 of 20
14. Question
A tank can be filled by three pipes A, B and C in 12 hours. All the pipes were opened for 3 hours and then pipe C was closed. A and B filled the remaining tank in 15 hours. Find the time taken by pipe C alone to completely fill the tank?
Correct
Answer: d)
(A + B + C)’s one hour work = (1/12)
(A + B + C)’s 3 hour work = (3/12) = 1/4
Remaining = 3/4
(3/4)*(A + B)’s whole work = 15
(A + B)’s whole work = 15*(4/3) = 20 hours
C’s one hour work = (1/12) – (1/20) = (20 – 12)/(20*12)
= > (1/30)
C alone can complete the tank in 30 hours.
Incorrect
Answer: d)
(A + B + C)’s one hour work = (1/12)
(A + B + C)’s 3 hour work = (3/12) = 1/4
Remaining = 3/4
(3/4)*(A + B)’s whole work = 15
(A + B)’s whole work = 15*(4/3) = 20 hours
C’s one hour work = (1/12) – (1/20) = (20 – 12)/(20*12)
= > (1/30)
C alone can complete the tank in 30 hours.
Question 15 of 20
15. Question
A customer sold an article at 24% discount on the marked price, yet he got 15% profit on the cost price. If the cost price of the article is Rs. 152, then selling price is what percent of marked price?
Correct
Answer: c)
MP*(76/100) = 152*(115/100)
MP = 152*(115/100)*(100/76)
MP = Rs. 230
SP = 152*(115/100) = 174.80
Required % = (174.80/230)*100 = 76 %
(Or)
SP = MP * (100-Discount %)/100
SP/MP*100 = 100 -24 = 76%
Incorrect
Answer: c)
MP*(76/100) = 152*(115/100)
MP = 152*(115/100)*(100/76)
MP = Rs. 230
SP = 152*(115/100) = 174.80
Required % = (174.80/230)*100 = 76 %
(Or)
SP = MP * (100-Discount %)/100
SP/MP*100 = 100 -24 = 76%
