**Answers & Solutions:**

**1) Answer (B)**

Let us assume the present age of Farheen = x years

So present age of Ramesh will be = x + 16 years

Ramesh’s age after 8 years will be = x+16+8 = x+24 years

Farheen’s age 8 years ago = x – 8 years

$\Rightarrow$ x+24 = 2*(x-8)

$\Rightarrow$ x= 40 years

So the present age of Farheen will be 40 years.

**2) Answer (D)**

$\Large\frac{169.87^{2}-13.94^{2}}{183.87}$ $\large+$ $\Large\frac{3211.96}{44.002}\simeq \frac{170^{2}-14^{2}}{184}$ $\large+$ $\Large\frac{3212}{44}$

$= \Large\frac{(170+14)(170-14)}{184}$ $+$ $73$

$= \Large\frac{184\times156}{184}$ $+$ $73$

$= 156+73 = 229$

**3) Answer (A)**

Let the number of students be ‘x’

Given that the average is increased by $\Large\frac{1}{3}$ due to the increase of $18$ marks ( $64$ $-$ $46$ $=$ $18$ marks )

Actual increase in marks $=$ $\Large\frac{1}{3}$ $\times$ x

$\Rightarrow$ $\Large\frac{1}{3}$ $\times$ x $=$ $18$

$\therefore$ Number of students(x) $=$ $54$

**4) Answer (D)**

In Q1 we have x*1.85*0.85=357

x=357/(1.85*0.85)

x=227

In Q2 we have x*1.82*0.88=355.5

x=355.5/(1.82*0.88)

x=220

Therefore Q1>Q2

**5) Answer (B)**

Number of students scoring in between 0-20 = Total students appeared – Number of students scoring above 20

Number of students scoring in between 20-40 = Number of students scoring above 20 – Number of students scoring above 40

Number of students scoring in between 40-60 = Number of students scoring above 40 – Number of students scoring above 60

Number of students scoring in between 60-80 = Number of students scoring above 60 – Number of students scoring above 80

Number of students scoring in between 80-90 = Number of students scoring above 80 – Number of students scoring above 90

Number of students scoring in between 90-100 = Number of students scoring above 90

Thus, the required ratio = 2085:1525 = 417:305

Hence, option B is the correct answer.

General Knowledge Questions & Answers PDF

**6) Answer (D)**

let the maximum marks be ‘x’.

Ravi = 0.35x

passing marks = 0.35x + 7

Passing marks is also equal to 82 – 5 = 77 marks

Thus, 0.35x + 7 = 77

x = 200

Thus statements I and III both are required to answer the question.

Using statement II alone or with any other statement we cannot find the answer.

Hence, option D is right answer.

**7) Answer (C)**

Volume of the sphere of 20 cm radius = $\dfrac{4\pi}{3}\times 20^3$ = $\dfrac{32000\pi}{3}$

Volume of right-circular cone whose height is 20cm and radius of circular base is 15 cm.= $\dfrac{\pi}{3}\times 25^2*60$ = $12500\pi$

Hence, we can say that Quantity 1 < Quantity 2. Option C is the correct answer.

**8) Answer (B)**

The lengths 140 cm, 280 cm and 420 cm should be the multiples of the length of the rod. The maximum possible length of the rod will be equal to the HCF of these 3 numbers.

140 = 2*70

280 = 4*70

420 = 6*70

As we can see, the HCF is 2*70 = 140 cm.

Therefore, option B is the right answer.

**9) Answer (E)**

Simple interest paid to bank = 1000*.22*2 = Rs. 440

Compound interest paid to bank = $1000(1 + \dfrac{20}{100})^2 – 1000$ = Rs. 440

Hence, we can say that Quantity 1 = Quantity 2. Option E is the correct answer.

**10) Answer (B)**

Monthly average of A = $\dfrac{10000 * 4}{12}$ = Rs. $\dfrac{10000}{3}$

Monthly average of C = $\dfrac{10000 * 12}{12}$ Rs. 10000

So, monthly average of A is $\frac{1}{3}$ of the monthly average of C

So, A’s profit = $\frac{1}{3}$ of C’s profit = Rs. 400

Hence, option B is the correct answer.

**11) Answer (A)**

Let 1 bottle of apple juice fill ‘a’ glasses and 1 bottle of mango juice fill ‘m’ glasses.

We have 5a + 9m = 71 and 7a + 11m = 93.

Solving we get a = 7 and m = 4.

So 3 bottles of apple juice and 4 bottles of mango juice will fill = 7*3 + 4*4 = 37 glasses

Hence, option A is the right choice.

**12) Answer (B)**

A can do the work in 20 days

B can do the work in 25 days

C can do the work in 40 days

Total work = LCM of 20,25,40 $=$ 200 units

Efficiency of A $=$ $\Large\frac{200}{20}$ $=$ 10 units/day

Efficiency of B $=$ $\Large\frac{200}{25}$ $=$ 8 units/day

Efficiency of C $=$ $\Large\frac{200}{40}$ $=$ 5 units/day

Let the number of days required to complete the work be ‘X’ days

Total work done by A in X days $=$ 10 $\times$ X $=$ 10X units

Total work done by C in X days $=$ 5 \times X $=$ 5X days

B left 4 days before completion

Total work done by B in (X – 4) days $=$ 8(X – 4) $=$ (8X – 32) units

$\therefore$ 10X + 5X + 8X – 32 $=$ 200

23X – 32 $=$ 200

$\therefore$ X $=$ $\Large\frac{232}{23}$ $=$ 10$\Large\frac{2}{23}$ days

**13) Answer (D)**

7*4+5 = 28+5 = 33

33*4+5 = 132+5 = 137

137*4+5 = 548+5 = 553

553*4+5 = 2212+5 = 2217

2217*4+5 = 8868+5 = 8873

Hence, 8871 must be replaced by 8873

**14) Answer (A)**

When a dice is rolled we get outcome from (1,2,3,4,5,6) so favourable cases (Sum = 2,3,4)

Favourable cases = (1,1) (1,2) (2,1) (1,3) (3,1) (2,2)

Total cases = 6*6 = 36

So probability $= \frac{ \text{Favourable cases}}{\text{Total cases}}$

$= \frac{6}{36} =\frac{1}{6}$

**15) Answer (D)**

Let us assume that on a normal day he sells milk at x rupee per litre and he sells y litre of milk

So revenue generated on normal day = x*y = xy

He mixed water with milk in ratio of 2:5 so net quantity = $\frac{2+5}{5} * y$ = 1.4y

New selling price during summer = 1.2x rupees per litre

So revenue generated in summers = 1.4y * 1.2x = 1.68xy

Hence we can say that revenue will go up by 68 percent.

**16) Answer (E)**

7 = 1 + 1 + 5 = 2 + 2 + 3 = 3 + 3 + 1 = 1 + 2 + 4

Thus, the probability that sum of the number on the faces of the dice is 7 = (3C1+3C1+3C1+3!)/216 = 15/216 = X

10 = 6 + 3 + 1 = 6 + 2 + 2 = 5 + 3 + 2 = 4 + 4 + 2 = 4 + 3 + 3 = 1 + 4 + 5

Thus, the probability that sum of the number on the faces of the dice is 14 = (3C1+3C1+3C1+3!)/216 = 15/216 = Y

Hence, X=Y

Hence, option E is the correct answer.

**17) Answer (D)**

Let us check the options.

Option (A): Average cost price of the mixture = $\dfrac{200+560+1260}{2+4+7}$ = Rs. 155.38

Option (B): Average cost price of the mixture = $\dfrac{100+700+1800}{1+5+10}$ = Rs. 162.50

Option (C): Average cost price of the mixture = $\dfrac{100+280+540}{1+2+3}$ = Rs. 153.33

Option (D): Average cost price of the mixture = $\dfrac{200+700+900}{2+5+5}$ = Rs. 150

Therefore, option D is the correct answer.

**18) Answer (E)**

Let the distance between Ram’s office and home = 150d

Then his original speed = $\frac{150d}{30}$ = 5d

Distance that Ram covered at (1/3)rd of original distance = $\frac{150d}{3}$ = 50d

(4/5)th of original speed = $\frac{4}{5} * 5d$ = 4d

Time taken by Ram to cover this distance = $\frac{50d}{4d} = 12.5$minutes

Remaining distance = 150d – 50d = 100d

(2/5)th of original speed = $\frac{2}{5}*5d$ = 2d

Time taken by Ram to cover the remaining distance = $\frac{100d}{2d}$ = 50 minutes

Hence total time taken by Ram = 12.5 + 50 = 62.5 minutes

**19) Answer (C)**

Length = 5 m , Breadth = 3 m and Height = 8 m

To find the cost of painting the walls of the room, we should know the cost of painting and the area of door and window.

Area of 4 walls (Curved Surface Area of cuboid) = $2h(l+b)$

= $(2 \times 8)(5+3) = 16 \times 8 = 128$ $m^2$

From I & II : Cost = Rs 25 per square meter

Area of window = $2.25$ $m^2$

and Area of door = $2 \times 2.25 = 4.5$ $m^2$

Thus, area to be painted = $128 – 2.25 – 4.5 = 121.25$ $m^2$

$\therefore$ Cost of painting 4 walls = $25 \times 121.25 = Rs$ $3031.25$

Thus, statement III is redundant.

=> Ans – (C)

**20) Answer (E)**

Let ‘x’ be the number of students who took all the three electives and ‘y’ be the number of students who took only management as an elective.

We get following venn diagram –

Considering students who took management as an elective we have,

y + x + 84 + 75 = 238

x + y = 79

Considering students who took history as an elective we have,

137 – y + x + 84 + 52 = 240

y – x = 33

Adding both the equation we get,

2y = 112

y = 56

So, x = 23

So, number of students who took all the three electives = 23

Number of students who took only management = 56

Number of students who took only history = 137 – 56 = 81

So, the number of students who took only physics = 450 – 240 – 56 – 75 = 79

Thus, we get following venn diagram –

Number of students who selected both management and physics as elective = 75 + 23 = 98

Hence, option E is the correct choice.
