Mindtree Aptitude Questions & Answers For Freshers By Sections
1. The average temperature in Delhi for the first four days of the month was reported as 58 degrees. It reported as 60 degrees for 2nd, 3rd, 4th and 5th days. The ratio of the temperatures of 1st and 5th day was 7: 8. Find the temperature on the first day.
A. 42 degrees
B. 46 degrees
C. 56 degrees
D. 68 degrees
Answer – C. 56 degrees
Explanation:
A+B+C+D = 58*4
B+C+D+E = 60*4
Subtract both, E-A = 8
So 8x – 7x = 8, x = 8
So temperature of A(1st day) = 7x = 7*8 = 56 degrees
2. In a group of 8 boys, 2 men aged at 21 and 23 were replaced, two new boys. Due to this the average cost of the group increased by 2 years. What is the average age of the 2 new boys?
A. 17
B. 28
C. 23
D. 30
Answer – D. 30
Explanation:
Average of 8 boys increased by 2, this means the total age of boys increased by 8*2 = 16 yrs
So sum of ages of two new boys = 21+23+16 = 60
Average of these = 60/2 = 30
3. One year ago the ratio between Rahul salary and Rohit salary is 4:5. The ratio between their individual salary of the last year and the current year is 2:3 and 3:5 respectively. If the total current salary of Rahul and Rohit is 4300. Then find the current salary of Rahul.
A. 1200
B. 1800
C. 1600
D. 2000
Answer – B. 1800
Explanation:
4x and 5x is the last year salary of Rahul and Rohit respectively
Rahul last year to Rahul current year = 2/3
Rohit last year to Rohit current year = 3/5
Current of Rahul + current of Rohit = 4300
(3/2)*4x + (5/3)*5x = 4300.
X = 300.
So Rahul current salary = 3/2 * 4* 300 = 1800
4. A bag contains 25p coins, 50p coins and 1 rupee coins whose values are in the ratio of 8:4:2. The total values of coins are 840. Then find the total number of coins
A. 260
B. 280
C. 220
D. 240
Answer – B. 280
Explanation:
Value is given in the ratio 8:4:2.
(8x/0.25) + (4x/0.5) + (2x/1) = 840.
X = 20. Total amount = 14*20 = 280
5. Two vessels contain an equal quantity of solution contains milk and water in the ratio of 7:2 and 4:5 respectively. Now the solutions are mixed with each other then find the ratio of milk and water in the final solution?
A. 11:5
B. 11:6
C. 11:7
D. 11:9
Answer – C. 11:7
Explanation:
milk = 7/9 and water = 2/9 – in 1st vessel
milk = 4/9 and water = 5/9 – in 2nd vessel
(7/9 + 4/9)/ (2/9 + 5/9) = 11:7
6. 8 4.5 5.5 13 56 ?
A. 456
B. 436
C. 526
D. 556
Answer – A. 456

18. A can do a work in 32 days. B who is 60 percent more efficient than A. Find how much time they will take together to do the same work?
A. 150/13 days
B. 160/13 days
C. 170/3 days
D. 190/3 days
Answer – B. 160/13 days
Explanation:
A’s one-day work = 1/32
Therefore, B one day work = (160/100)*1/32 = 1/20
Then, B will take 20 days to complete the work.
So Both A and B will take = (32*20)/52 = 160/13 days
Hence it is proved.
19. 50 men could complete work in 200 days. They worked together for 150 days, after that due to bad weather the work is stopped for 25 days. How many more workers should be employed so as to complete the work in time?
A. 25
B. 35
C. 50
D. 60
Answer – C. 50
Explanation:
Let additional workers be P
Then, (50*150)/(50*200) = 3/4 of the work is already completed and now only 1/4 of the work is to be done.
Therefore, 1/4 = ((50 + P) * 25)/50*200, solve for p, we get P = 50
Hence, more workers should be employed so as to complete the work in time = 50
20. Abhishek takes thrice as long to row a distance against the stream as to row the same distance in favor of the stream. The ratio of the speed of the boat in still water and stream is
A. 1: 2
B. 2: 1
C. 2: 3
D. 3: 1
Answer – B. 2: 1
Explanation:
speed downstream = x kmph
Speed upstream = 3x kmph
(3x+x)/2 : (3x-x)/2
4x/2 : 2x/2 = 2: 1
21. A boat can travel 4.2 km upstream in 14 min. If the ratio of the speed of the boat in still water to the speed of the stream is 7:1. How much time will the boat take to cover 17.6 km downstream?
A. 32 min
B. 48 min
C. 56 min
D. 44 min
Answer – D. 44 min
Explanation:
Speed = 7x: x
Downstream = 8x; upstream = 6x
Upstream speed = 4.2*60/14 = 18 kmph
6x = 18
X = 3
Downstream = 8*3 = 24
Time taken for 17.6 km = 17.6*60/24 = 44 min
22. A man can row at 4 kmph in still water. If the velocity of the current is 1 kmph and it takes him 1 hour to row to a place and come back. how far is that place?
A. 1.5 km
B. 1.8 km
C. 2.6 km
D. 3.2 km
Answer – B. 1.8 km
Explanation:
Let the distance is x km
Rate downstream = 4 + 1 = 5 kmph
Rate upstream = 4 – 1 = 3 kmph
then
x/5 + x/3 = 1
3x + 5x = 15
x = 15/8 = 1.8 km
23. A boat takes 30 hours for traveling downstream from point A to point B and coming back to point C midway between A and B. If the velocity of the stream is 2 kmph and the speed of the boat in still water is 15 kmph, what is the distance between A and B?
A. 308 km
B. 316 km
C. 342 km
D. 356 km
Answer – A. 308km
Explanation:
The velocity of the stream = 2 kmph
The speed of the boat in still water is 15 kmph
Speed downstream = (15+2) = 17 kmph
Speed upstream = (15-2) = 13 kmph
Let the distance between A and B be x km
x/17+(x/2)/13=30
x/17+x/26=30
43x/442=30
x=30*442/43 = 308.37 = 308 km
the distance between A and B = 308 km
24. Varun got 5000 as his share out of the total profit of 9000. Dhaval had invested 3000 rupees for 6 months while Varun invested for the whole year. Find the amount invested by Varun.
A. 1875
B. 1975
C. 2125
D. 2275
Answer – A. 1875
Explanation:
Amount invested by Varun = P
12 P: 3000*6
P:1500
So Varun share = [p/(1500+p)]*9000 = 5000
P = 75*25 = 1875
Therefore, Amount invested by Varun is 1875
25. A and B invested in a business in which A invest 250 rupee more than B. B invested for 6 months while A invested for 4 months. If A gets 200 more than B out of a total profit of 1000. Then the total amount invested in the business.
A. 550
B. 650
C. 750
D. 850
Answer – B. 650
Explanation:
Let B invest ‘x’ rupees so A will invest (x+250)
Total investment made by A = (x+250)*4 and by B = 6x
According to the problem- [[4(x+250) – 6x]/(1000+ 10x)]*1000 = 200.
X = 200. Total investment = 200+250+200 = 650
