Question 12 of 20
12. Question
Manoj, Rohan, Anuj and Sohan start running around a circular field having circumference 150m at the same time from the same point. Speeds of Manoj, Rohan, Anuj and Sohan are 3 m/minute, 5m/minute, 6 m/minute and 10 m/minute. Find after how much time, they will meet again at the same point for the first time?
Correct
Answer C
Time taken by Manoj to complete one round = 150/3 = 50 minutes
Time taken by Rohan to complete one round = 150/5 = 30 minutes
Time taken by Anuj to complete one round = 150/6 = 25 minutes
Time taken by Sohan to complete one round = 150/10 = 15 minutes
LCM of 50, 30, 25 and 15 = 150minutes
Hence, they will meet again after 150 minutes.
Incorrect
Answer C
Time taken by Manoj to complete one round = 150/3 = 50 minutes
Time taken by Rohan to complete one round = 150/5 = 30 minutes
Time taken by Anuj to complete one round = 150/6 = 25 minutes
Time taken by Sohan to complete one round = 150/10 = 15 minutes
LCM of 50, 30, 25 and 15 = 150minutes
Hence, they will meet again after 150 minutes.
Question 13 of 20
13. Question
The population of a town before three years was 44000. In first year it increased by 15%, in the second year again increased by 20% and in the third year decreased by 10%. Find the difference between present population of the town and the population of the town before three years?
Correct
Answer B
Present population of the town = 44000 x 115/100 x 120/100 x 90/100 = 54648
Required difference = 54648 – 44000 = 10648
Incorrect
Answer B
Present population of the town = 44000 x 115/100 x 120/100 x 90/100 = 54648
Required difference = 54648 – 44000 = 10648
Question 14 of 20
14. Question
Ratio of the present ages of Umang and his wife is 9:8. Four years ago, ratio of their ages was 8:7. After how many years ratio of their ages will be 13:12?
Correct
Answer B
Let the present ages of Umang and his wife are 9x and 8x respectively.
(9x – 4)/(8x – 4) = 8/7
=> 63x – 28 = 64x – 32
=> x = 4
Present age of Umang = 9x = 9 * 4 = 36 years
Present age of his wife = 8x = 8 * 4 = 32 years
Let after p years ratio of their ages will be 13:12
(36 + p)/(32 + p) = 13/12
=> 432 + 12p = 416 + 13p
=> p = 432 – 416
=> p = 16 years
Incorrect
Answer B
Let the present ages of Umang and his wife are 9x and 8x respectively.
(9x – 4)/(8x – 4) = 8/7
=> 63x – 28 = 64x – 32
=> x = 4
Present age of Umang = 9x = 9 * 4 = 36 years
Present age of his wife = 8x = 8 * 4 = 32 years
Let after p years ratio of their ages will be 13:12
(36 + p)/(32 + p) = 13/12
=> 432 + 12p = 416 + 13p
=> p = 432 – 416
=> p = 16 years
Question 15 of 20
15. Question
A man rows to a place 48 km apart and back in 16 hours. He finds that he can row 6 km downstream and 4 km upstream in the same time. The speed of the stream is?
Correct
Answer A
Let the time of downstream and upstream x.
Speed of downstream= 6/x km/hr
Speed of upstream= 4/x km/hr
48/(6/x) + 48/(4/x) = 16
=>20x=16
=> x= 4/5 =0.8
Speed of downstream= 6/x = 6/0.8 =7.5 km/hr
Speed of upstream= 4/x = 4/0.8 = 5 km/hr
The speed of the stream is,
=> ½ ( 7.5- 5)
=> 5/2 =1.25 km/hr
Incorrect
Answer A
Let the time of downstream and upstream x.
Speed of downstream= 6/x km/hr
Speed of upstream= 4/x km/hr
48/(6/x) + 48/(4/x) = 16
=>20x=16
=> x= 4/5 =0.8
Speed of downstream= 6/x = 6/0.8 =7.5 km/hr
Speed of upstream= 4/x = 4/0.8 = 5 km/hr
The speed of the stream is,
=> ½ ( 7.5- 5)
=> 5/2 =1.25 km/hr
Question 16 of 20
16. Question
Directions (Q. 16-20): The following pie-chart shows the distribution of profit of six banks in 2015, 2016 and 2017
What is the difference between the profit of 2015 in Bank B and the profit of 2016 in Bank F?
Correct
Answer A
Difference = (80 × 86.4)/360 – (90 × 32.4)/360
= 19.2 – 8.1
= 11.1 lakh
Incorrect
Answer A
Difference = (80 × 86.4)/360 – (90 × 32.4)/360
= 19.2 – 8.1
= 11.1 lakh
