Indian Army Agniveer Mock Test - 2 - Indian Army Agniveer MCQ

Given:
Time taken by 6 men to complete a piece of work =10 days
If a person takes x days to complete a work, part of the work
completed by him in one-day = 1/x
Time taken by 1 man = 6×10 = 60 days
∴ The time taken by 4 men to complete the work = 60/4 = 15 days.

Given:
Students failed in school X =30%
Number of students in school Y =150% more than number of students in school X
Students passed in both schools =80%
Let number of students in school X be 100x.
Number of failed students in school X =30% of 100x=30x
Number of passes students in school Y =(100x–30x)=70x
Number of students in school Y =100x+150% of 100x
=100x+150x=250x
Total number of students in school X and school Y =100x+250x=350x
Number of passes students in both schools =80% of 350x=280x
So, number of passed students in school Y =280x–70x=210x
Number of failed students in school Y =250x–210x=40x
Percentage of failed students in school Y = (40x/250x) x 100% = 16%
∴ The percentage of students who failed from school Y is 16%.

Given:
Equation = 

Relative speed, if opposite directions = (x + y) km/hr
Relative speed of both men, if they running opposite direction.
= 10+20 = 30 km/hr
= 30 x (5/18)m/s
Time taken to meet each other =  seconds

Given:
Rate of interest = 2.5% per month
Amount paid after 6 months = Rs. 13110
Amount, A = P+SI
Simple interest, 
Where P→ Principal, R→ rate of interest, T→ time
Suppose the sum borrowed be Rs. x

⇒ Amount of interest = 0.15×11400
= Rs. 1710

Given:
Ratio of radius of two right circular cylinders = 3:2
Ratio of their volumes = 27:16
As we know,
Volume of right circular cylinder = πr²h
let the height of both cylinder be h₁ and h₂

∴ The ratio of their heights is 3:4.

The smallest number which is divisible by all the odd numbers up to 15 would be the L.C.M of all the odd numbers up to 15.
∴ Required number = L.C.M of 1,3,5,7,9,11,13,15
= 45045

Given,
Right-angled triangle, the square of the hypotenuse is twice the product of the other sides.
As we know,
A triangle whose two sides are equal, called isosceles triangle.
A triangle whose one angle is equal to 90°, called right angled triangle.
Let given sides are p, b and h where p = perpendicular, b = base and h = hypotenuse.
Now, p² + b² = h² ---- (1) [Right angles triangle property]
According to question,
h² = 2 × p × b...(2)
Putting (2) in (1), we get
P² + b² = 2pb
⇒ p² + b² – 2pb = 0
⇒ (p - b)2 = 0
⇒ p = b
The other two sides are equal. Therefore, the triangle is an isosceles triangle.

Given:
Two angles of a triangle are equal
The third angle = 70°
Formula Used:
Sum of the angle of the triangle = 180°
Calculations:
⇒ Let the unknown angle be x
⇒ 2nd angle = x
⇒ 3rd angle = 70°
so,
⇒ Sum of the angle of the triangle = 180°
⇒ x + x + 70 = 180
⇒ 2x = 180 - 70 = 110
⇒ x = 55°
⇒ Hence, The unknown angle of the triangle is 55°.

Calculation:

⇒ 29/6, 61/9,71/9,77/10
By making the denominator same we have,
⇒ 435/90, 610/90, 710/90, 693/90
Out of the above numbers the greatest is 710.
∴ The correct answer is 7(8/9).

Formula Used:
Area of Circle = π × r²
Circumference of Circle = 2π × r
Calculation:

Let radius of ground be r & radius of road be R
Difference between circumference = 44m
Using above formula -
⇒ 2π (R - r) = 44
⇒ 2π (R - 7)= 44
⇒ (44/7)(R - 7) = 44
⇒ R - 7 = 7
⇒ R = 14 m
⇒ Area of road = π (R² - r²) = π (14² - 7²) 
⇒ Area of road =  (22/7)× 147 = 462 m²
∴ The correct answer is 462 m²

Given:
84 ÷ 32 × 8 - 15 ÷ 8 × (19 - 35)
Concept used:

Calculation:
84 ÷ 32 × 8 - 15 ÷ 8 × (19 - 35)
⇒ 84 ÷ 32 × 8 - 15 ÷ 8 × (- 16)
⇒ 21/8 × 8 - (15/8) × (- 16)
⇒ 21 + 30
⇒ 51
∴ The required answer is 51.

Given:
a + b + c = 10 and a² + b² + c² = 4
Concept Used:
(a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca 
Calculation:
⇒ Using the formula (a + b + c)² we get,
⇒ (a + b + c)² = a² + b² + c² + 2ab + 2bc + 2ca 
⇒ (10)² = 48+ 2(ab + bc + ca)
⇒ 100 – 48 = 2(ab + bc + ca)
⇒ ab + bc + ca = 52/2 = 26
Therefore, the value of ab + bc + ca is 26.

Given:
The price of cooking oil has increased by 25%.
Formula Used:
Expenditure = Price × Consumption
Calculation:
Let, the previous budget was Rs 100.
As it increased by 25%, it became Rs125
Since the family has to maintain the previous budget.
⇒ Rs 125 should be reduced to Rs 100
⇒ Rs 1 should be reduced to Rs 100/125
⇒ Rs 100 should be reduced to Rs (100/125) × 100 = Rs 80
⇒ (100- 80 ) = 20% 
∴The answer is 20% .

Calculation:
⇒ 42 - 25 = 17
⇒ 72 - 55 = 17
⇒ 84 - 67 = 17
Now, LCM (42, 72, 84) = 504
Hence, required number = 504 - 17 = 487
∴ The correct answer is 487.
