## Answers With Solutions

#### 1. Ans. B.

__Solution:__Let total monthly salary = 100 Rs.

Expenses on Food = 100 × 30% = 30 Rs

Expenses on Dress = 70 × 20% = 14 Rs

Expenses on misc = 56 × 25% = 14 Rs

Saving = 42 Rs

Total Salary = 1764/42 × 100 = 42 Rs

#### 2. Ans. D.

__Solution:__
Let Antra’s income = 100 Rs

Mitali’s income = 100 × 90% = 90 Rs

Mohan’s income = 90 × 120% = 108 Rs

% less = 8/100 × 100 = 8%

Mitali’s income = 100 × 90% = 90 Rs

Mohan’s income = 90 × 120% = 108 Rs

% less = 8/100 × 100 = 8%

#### 3. Ans. A

__Solution:__According to the question,

(a+2000) × 20% - a × 10% = 840

a/5 + 400 – a/10 = 840

a/10 = 840 – 400

a/10 = 440

a = 4400

Ratio = 4400 : 6400 = 11:16

#### 4. Ans. C.

__Solution:__Let total work is 36.

Vansh’s 1 day work = 36/36 = 1

Vansh’s 9 day work = 9

Tanisha’s 1 day work = 36/18 = 2

According to the question,

Let Tanisha and Vansh can do the work in x days.

9 + (1 + 2) x =36

9 + 3x = 36

3x = 36 – 9

3x = 27

x = 9 days

#### 5. Ans. C.

__Solution:__Total Distance = 120 + 150 + 90 = 360 km

Total time = 120/15 + 150/30 + 90/18 = 8 + 5 + 5 = 18 hours

Average speed = 360/18 = 20 km/h

#### 6. Ans. E.

__Solution:__Consonant = HDLGHT

Total ways = 4! × 6! = 4 × 3 × 2 × 1 × 6 × 5 × 4 × 3 × 2 × 1 = 17280

#### 7. Ans. B.

__Solution:__Probability = Favourable outcomes/ Total outcomes = 6C2 × 5C315C5

=6×52×1×5×4×33×2×115×14×13×12×115×4×3×2×1 = 50/1001

#### 8. Ans. D.

__Solution:__Area of the circle = π r2

38.5 = 22/7 r2

r2 = 12.25

r = 3.5

Side of square = 3.5 + 2.5 = 6cm

Perimeter = 4 × 6 = 24cm

#### 9. Ans. E.

__Solution:__Milk = 72 × 75% = 54 litre

Water = 72 – 54 = 18 litre

Milk in new mixture = 54 – 9×75% + 9 = 54 – 6.75 + 9 = 56.25 litre

% = 56.25/ 72 × 100 = 78.125%

### 10. Ans. A.

__Solution:__Total age = 28 × 2 = 56 years

According to the question,

5x+4 + 7x+4 = 56

12x + 8 = 56

12x = 56 – 8

12x = 48

x = 4

Present age = 20 + 4 = 24, 28 + 4 = 32

Ratio after 8 years = 24 + 8 : 32 + 8 = 32 : 40

= 4:5
