An article is marked at Rs 32000 and it is double that of its cost price. If the shopkeeper gives a discount of Rs 8000, what is the profit percentage on that article?

Correct

Answer- 4) 50%
Explanation-
Cost price of the article = 32000/2 = Rs 16000
Marked price of the article = 32000 – 8000 = Rs 24000
Profit % = (24000 – 16000)/16000 × 100 = 800000/16000 = 50%

Incorrect

Answer- 4) 50%
Explanation-
Cost price of the article = 32000/2 = Rs 16000
Marked price of the article = 32000 – 8000 = Rs 24000
Profit % = (24000 – 16000)/16000 × 100 = 800000/16000 = 50%

The speed of boat in still water is 16 km/h more than that of stream. It travels 112 km downstream in 2.8 hours. What is the speed of the stream?

Correct

Answer- 2) 12 km/h
Explanation-
Let the speed of stream is x km/h.
Speed of boat in still water = (x + 16) km/h
Therefore,
112/(x + x + 16) = 2.8
2x + 16 = 40
2x = 24, x = 12 km/h

Incorrect

Answer- 2) 12 km/h
Explanation-
Let the speed of stream is x km/h.
Speed of boat in still water = (x + 16) km/h
Therefore,
112/(x + x + 16) = 2.8
2x + 16 = 40
2x = 24, x = 12 km/h

Perimeters of two squares are 84 m and 212 m respectively. What is the perimeter of the third square whose side is equal to the difference between the sides of those two squares?

Correct

Answer- 2) 128 m
Explanation-
Side of first square = 84/4 = 21 m
Side of second square = 212/4 = 53 m
Side of the third square = 53 – 21 = 32 m
Perimeter of the third square = 32 × 4 = 128 m

Incorrect

Answer- 2) 128 m
Explanation-
Side of first square = 84/4 = 21 m
Side of second square = 212/4 = 53 m
Side of the third square = 53 – 21 = 32 m
Perimeter of the third square = 32 × 4 = 128 m

A mixture of milk and water amounts 96 l and milk is 72 l out of the total mixture. 36 l of the mixture is taken out and 10 l of the water is added. What is the respective ratio of milk and water in the mixture now?

Correct

Answer- 1) 9:5
Explanation-
Ratio of milk to water originally = 72/24 = 3:1
Ratio of milk to water will stay the same after taking 36 l of mixture out.
Now,
Amount of milk in mixture = (96 – 36)/4 × 3 = 45 l
Amount of water in mixture = 60 – 45 = 15 l
Ratio of milk to water after adding 10 l of water = 45/25 = 9:5

Incorrect

Answer- 1) 9:5
Explanation-
Ratio of milk to water originally = 72/24 = 3:1
Ratio of milk to water will stay the same after taking 36 l of mixture out.
Now,
Amount of milk in mixture = (96 – 36)/4 × 3 = 45 l
Amount of water in mixture = 60 – 45 = 15 l
Ratio of milk to water after adding 10 l of water = 45/25 = 9:5

B is 14 years older to A and C is five years younger to A. Sum of present ages of B and C is 53 years. What is the ratio of present age of A to the age of B 3 years ago?

Correct

Answer- 5) 2:3
Explanation-
Let the present age of A is x years
Then, present age of B = (x + 14) years
Present age of C = (x – 5) years
We have,
x + 14 + x – 5 = 53
2x = 44, x = 22 years
Present age of A = 22 years
Age of B 3 years ago = 22 + 14 – 3 = 33 years
Required ratio = 22/33 = 2:3

Incorrect

Answer- 5) 2:3
Explanation-
Let the present age of A is x years
Then, present age of B = (x + 14) years
Present age of C = (x – 5) years
We have,
x + 14 + x – 5 = 53
2x = 44, x = 22 years
Present age of A = 22 years
Age of B 3 years ago = 22 + 14 – 3 = 33 years
Required ratio = 22/33 = 2:3

Correct

Answer- 3) 5:10 pm
Explanation-
Time taken by Harry to reach home with original speed = 1 hour 15 min = 5/4 hours
Distance between his school and home = 12 × 5/4 = 15 km
Time taken to reach home with reduced speed = 15/9 = 5/3 hours = 1 hour 40 min
Time at which he will reach home = 3:30 + 1:40 = 5:10 pm

Incorrect

Answer- 3) 5:10 pm
Explanation-
Time taken by Harry to reach home with original speed = 1 hour 15 min = 5/4 hours
Distance between his school and home = 12 × 5/4 = 15 km
Time taken to reach home with reduced speed = 15/9 = 5/3 hours = 1 hour 40 min
Time at which he will reach home = 3:30 + 1:40 = 5:10 pm

A invested Rs x and B invested Rs (x + 3000) in a business. A left the business after 6 months. Find the value of x if at the end of year, profit was distributed between A and B in the ratio 5:12 respectively.

A can do a piece of work in 15 days and B can do the same work in 75 days. In how many days they will complete the 20% of the work working together?

Correct

Answer- 1) 2.5 days
Explanation-
LCM of 15 and 75 = 75
Total work = 75
Work done by A in one day = 75/15 = 5
Work done by B in one day = 75/75 = 1
Time taken by them to complete 20% of the work = 20% of 75/(5 + 1) = 15/6 = 2.5 days

Incorrect

Answer- 1) 2.5 days
Explanation-
LCM of 15 and 75 = 75
Total work = 75
Work done by A in one day = 75/15 = 5
Work done by B in one day = 75/75 = 1
Time taken by them to complete 20% of the work = 20% of 75/(5 + 1) = 15/6 = 2.5 days
