- Question
- Alok started a business with Rs. 75000. After 3 months Chandan also joined him with Rs. 60000. If at the end of the year, the profit is Rs. 16000. What is the share of Chandan in the profit?
Options- A. Rs. 6000
- B. Rs. 10000
- C. Rs. 8000
- D. Rs. 4500
- Correct Answer
- Rs. 6000
ExplanationRatio between the investment of Alok and Chandan
= (75000 x 12) : (60000 x 9)
= 900000 : 540000
= 90 : 54 = 5 : 3
Total profit = Rs. 16000
? Chandan's share = [3/(5 + 3)] x 16000
= Rs. 6000 - 1. A sum of Rs. 12000 deposited at compound interest becomes doubles after 5 years. After 20 years it will become?

Correct Answer: 192000
Explanation:
? 2P = P(1 +r/100)5
? (1 +r/100)5 = 2
? (1 + r/100)20 = 24 = 16
Thus, P(1 +r/100)20 = 16P
= Rs. (12000 x 16)
= Rs. 192000
Correct Answer: 6 hrs 28 min
Explanation:
Time taken to cover 600 km = 600/100 = 6 hrs.
Number of stoppages = 600/75 - 1 = 7
Total time of stoppages = 4 x 7 = 28 min
Hence, total time taken = 6 hrs 28 min.
Correct Answer: 12 kmph
Explanation:
Let the distance traveled be x km.
Then, x/10 - x/15 = 2
3x - 2x = 60 => x = 60 km.
Time taken to travel 60 km at 10 km/hr = 60/10 = 6 hrs.
So, Robert started 6 hours before 2. p.m. i.e., at 8 a.m.
Required speed = 60/5 = 12 kmph.
Correct Answer: 1:7
Explanation:
Let the speed of the trains be x and y respectively
length of train1 = 47x
length of train2 = 31y
Relative speed= x + y
Time taken to cross each other = 33 s
=>
= 33
=> (47x + 31 y) = 33(x + y)
=> 14x = 2y
=> x/y = 2/14 = 1/7
= 1:7
Correct Answer: ? 1890
Explanation:
Principle = ? 1089
? P/{(1 + 10/100) + (1 + 10/100)2 } = 1089
? P = {(1089 x 10/11) + (1089 x 100/121)} = (990 + 900) = ? 1890
Correct Answer: 144 km
Explanation:
Given a jeep travels a certain distance taking 6 hrs in forward journey
During the return journey, it takes 4 hrs with an increased speed 12 km/hr
Let 'x' be the distance.
Now, speed is given by distance/time.
Here the difference between both speeds = 12
=> x = 144 km
Therefore, the distance travelled by the jeep in forward or return journey is x = 144 km.
Correct Answer: 3.75 km
Explanation:
Let 'd' be the distance between A and B
K -time = d/10 + d/9 = 19d/90 hours
L -time = 2d/12 = d/6 hours
We know that, 10 min = 1/6 hours
Thus, time difference between K and L is given as 10 minutes.
=> 19d/90 - d/6 = 1/6
=> (19d-15d)/90 = 1/6
=> 4d/90 = 1/6
Thus,
d= 15/4 km = 3.75 km.
hence the distance between A and B is 3.75 km.
Correct Answer: 50 km
Explanation:
We know 60 min = 1 hr
Total northward Laxmi's distance = 20kmph x 1hr = 20 km
Total southward Prasanna's distance = 30kmph x 1hr = 30 km
Total distance between Prasanna and Laxmi is = 20 + 30 = 50 km.
Correct Answer: 42
Correct Answer: 24 kmph
Explanation:
Average speed=total distance/total time
Let distance to store be K
then, total time =(K/20)+(K/30)=K/12
and, total time =(2K)
so average speed= 2K / (K/12) = 24kmph.
