Indian Army Agniveer Mock Test - 1 - Indian Army Agniveer MCQ

Given,
Average of 60 observations = 42
As we know,

Average of 60 observations = 42
Sum of all 60 observations = 60×42 = 2520
New sum of all 60 observations if 50 is replaced by 20
= 2520−50+20 = 2490
∴ New average of 50 observations = 2490/60 = 41.5

Given,
A 's salary =60% more than B 's salary.
Let the salary of B be 100 .
A 's salary =100+60% of 100=160
B 's salary =(160−100)=60 less than 

= 37.5%
∴ The salary of B is 37.5% less than the salary of A.

The difference of the numbers = 34041 – 32506 = 1535
The number that divides both these numbers must be a factor of 1535.
307 is the only 3 digit integer that divides 1535.

We know that,
1km=1000m
1 hour =60×60sec
According to the question,
Distance =333km=333×1000m
Time =2 hour =2×60×60sec
We know that,
Speed = Distance/Time
So,

Let, x red marbles be added,

Let the two angles be A and B.
As we know,
Sum of two complementary angle =90∘
∠A+∠B=90º…(1)
∠A−∠B=40º… (2) (Given)
From equation (1) and (2), we get
∠A = 65º, ∠B= 25º

Given,
Compound interest in 2 years =16800
Rate =10%
Simple interest for Time =3 years
As we know,
Compound interest = Principal 

Simple interest  = 24,000
∴ The simple interest is Rs. 24,000 .

Given,
a : b : c = 3 : 4 : 7 
⇒ 3x + 4x + 7x =14x 
∴  a + b + c = 14x
⇒ c = 7x 
∴ (a + b + c) : c 
= 14x :7x 
= 2 : 1

Given:
The given number = 480
Concept used:
Positive integer multiples:  The multiples of an integer are all the numbers that can be made by multiplying that integer by any integer
Calculation:
According to the question
⇒ 480 = 32 × 3 × 5
⇒ 25 × 31 × 51
So, the number of positive factors of 480 is
⇒ (5 + 1) × (1 + 1) × (1 + 1)
⇒ (6 × 2 × 2) = 24
∴ The required answer is 24.

Given:
The outlet pipe can empty a cistern in 3 hrs.
Calculations:
According to question,
Time taken to fill whole cistern = 3 hours
Time taken to fill 2/3 part of the cistern = 2 hours
Hence, The Required value is 2 hours.

Given:
Principal = Rs. 1200
Rate = 10%, Time = 2 years
Formula used:

Where, P = Principal, R = Rate, T = Time
Calculation:
According to the question

⇒ Rs. (1452 - 1200) = Rs. 252
∴ The required interest is Rs. 252.

Given:
4 men or 7 women can finish a work = 60 days
Concept used:
Work = Efficiency × Time
Calculation:
4 men or 7 women can finish a work = 60 days
⇒ 4 men × 60 = 7 women × 60

Total work = (4 × 7 × 60) = 1680
Now, according to the question 8 men 7 women working together can complete the work in

∴ The required time is 20 days.

Given:
The equation x² − 4x + k = 0
Concept used:
Roots of a quadratic equation satisfy the equation, so by putting the value of one root, One can find the unknown variable and hence the other root.
Calculation:
Let us put x be 3 in the equation
So,
x² – 4x + k = 0
⇒ 9 – 12 + k = 0
⇒ k = 3
Putting the value of k in the equation, we get:
x² – 4x + 3 = 0
⇒ x² – 3x – x + 3 = 0
⇒ x(x – 3) – 1(x – 3) = 0
⇒ (x – 3)(x – 1) = 0
⇒ x = 3 and 1 
∴ The other root of the equation is 1.

Given:
The train takes 1 second to cross a telegraph post and 3 seconds to cross a platform 300 metres long.
Concept used:
1. While a train crosses a platform, it crosses the sum of its length and the length of the platform.
2. While a train crosses a telegraph post, it crosses its own length.
3. Distance = Speed × Time
Calculation:
Let the length and speed of the train be L metres and S m/s respectively.
According to the concept,
S × 1 = L
⇒ S = L      ....(1)
3S = (L + 300)
⇒ 3L = L + 300 (From 1)
⇒ 2L = 300
⇒ L = 150
∴ The length of the train is 150 metres.

Calculation:
We know that,
The largest four digit number is 9999
Divide this by 88, 55 is remainder this means if the number was 55 lesser, then it would be completely divisible by 88.
So, Largest 4 digit number divisible by 88 
⇒ 9999 - 55
⇒ 9944
∴ The largest four digit number that is divisible by 88 is 9944.
