## Selection process:

The placement process of IndiaMART consists of 4 rounds. These rounds are as follows:

• Aptitude Round
• Group Discussion
• Technical Interview
• HR Interview

## Aptitude round

The purpose of the aptitude round is to test the candidate's ability to solve the problems. Aptitude round contains the multiple choice questions of quantitative, verbal and reasoning.

## 1) How much time will it take for the amount Rs 450 to yield Rs 81 as interest at the rate of 4.5% per annum of simple interest?

1. 5
2. 4
3. 3
4. 2

Explanation:

Interest = 81
Rate = 4.5
Principle amount = 450
Simple interest = (principle amount X rate X time)/ 100
81 = (450 X 4.5 X t)/100
Time = 4 years

## 2) A sum of Rs 12500 amounts to Rs 15500 in 4 years at the rate of simple interest. What is the rate of interest?

1. 5%
2. 10%
3. 6%
4. 24%

Explanation:

New amount = old amount + interest
15500 = 12500 + interest
=> Interest = 3000
Simple interest = (principle amount X rate X time)/ 100
3000 = (12500 X rate X 4)/100
=> Rate = 6%

## 3) What will be the ratio of SI to be earned by a certain amount at the same rate of interest for 6 years and that of 9 years?

1. 2:3
2. 3:2
3. 4:5
4. 5:4

Explanation:

R1/R2 = ((principle amount X rate X time)/ 100)/( (principle amount X rate X time)/ 100)
=> ((p X 6 X r)/100)/((p X 9 X r)/100)
=> 6/9
=> 2/3
R1 : R2 = 2 : 3

## 4) A person borrows Rs 5000 for 2 years at 4% per annum simple interest. He lends it to another person at 25/4 % p.a for 2 years. Find his gain transaction per year?

1. 100
2. 200
3. 112.5
4. 225.4

Explanation:

Gain=((principle amount X rate X time)/ 100) for 1 year - ( (principle amount X rate X time)/ 100) for 2 year
= ((5000 X 2 X 25)/100 X 4) - ((5000 X 2 X 4)/100)
= 225 for 2 years
So 225/2 =112.5 for 1 year

## 5) A certain amount earns simple interest of Rs 1750 after a year had the interest been 2 % more than old, how much more interest would it have earned?

1. 4%
2. 6%
4. None

Explanation:

## 6) A 300m long train is running at a speed of 54 kmph. In what time, it will pass a bridge of 100m?

1. 45/3
2. 80/3
3. 100/3
4. 65/3

Explanation:

Length of train = 300m
Length of bridge = 100m
Speed= 54 kmph
=> 54 X (5/18) = 15 m/s
Speed = distance / time
15 = (300+100)/time
=> Time = 400/15
=> 80/3

## 7) A train covers 10 km in 10 min. If it takes 6 seconds to pass a telegraph post, the length of train is?

1. 200m
2. 250m
3. 100m
4. 150m

Explanation:

Distance = 10 km
Time = 10 min
Speed = distance / time
=(1000 X 10)/(10 X 60)
= 50/3
Speed = distance / time
50/3 = distance / 6
Distance= 100m

## 8) A train moves to pass a man and a bridge of 260m long in 8 sec and 10 sec respectively. What is the speed of the train?

1. 150 m/s
2. 130 m/s
3. 230 m/s
4. 250 m/s

Explanation:

Man:
Speed= distance/time
Distance= 8s
Bridge:
Speed = (train's length + bridge's length)/time
S= ((8s) + 260)/10
10s= 8s + 260
10s-8s=260
2s=260
S=130
Speed of train is 130 m/s

## 9) Two trains 100m and 200m long run at speed 60 kmph and 30 kmph respectively in opposite direction on parallel tracks. What time to cross?

1. 15
2. 17
3. 10
4. 12

Explanation:

Length of the first train= 100m
Length of the second train=200m
The Speed of the first train=60kmph
The Speed of the second train=30kmph
Total speed = 60 + 30
= 90 kmph
= (90 X 5)/18
= 25 m/s
Time =(first train length + second train length )/ speed
=300/25
=12 s

1. 30
2. 10
3. 40
4. 20

Explanation:

Present age = X
Future age = X + 15
Old age = X - 5
=> X + 15 = 5 (X - 5)
=> X + 15 = 5X - 25
=> 40 = 4X
=> X = 10 years

## 19) A is two years old than B who is twice as old as C. The total ages of A,B,C be 27. How old is B?

1. 35
2. 25

Xo for 39/6 hours
So X = (360 X 39)/6
=(39X5)
= 195
Min hand
6X60=360+30 = 390 min
360o for 60 min
Xo for 390 min
X= (360 X 30) / 60
X = 180
So 195 - 180 = 15

Downstream
Distance = 40 km
Time = 5 hr
Speed = d/t = 40/5
=8 kmph
Upstream
Distance = 20 kmph
Time = 5 hr
Speed = d/t = 20/5
= 4kmph
The velocity of current = (speed of downstream - speed of upstream)/2
= (8 - 4)/2 = 2 kmph

## 26) A boat takes 90 min less to travel 36 miles downstream than to travel the same distance upstream. If the speed of the boat is still water is 10 mphr the speed of the stream is?

1. 6
2. 5
3. 2
4. 1

Explanation:

Let x be the speed of the stream
Downstream= 10+x
Upstream = 10 -x
36/(10+x) - 36/(10-x) = 90/60
72x X 60 = 90(100 - x2)
144x=300-3x2
3x2 +144x-300=0
X= -50
or
X=2
The Speed of the stream is 2 mphr
