a) 110 %

b) 75 %

c) 90 %

**Answers :**

**1) Answer: a)**

Speed downstream = 5/x

Speed upstream = 4/x

60/(5/x) + 60/(4/x) = 27/2

X = ½

So, Speed downstream = 10 km/hr, Speed upstream = 8 km/hr

Rate of the stream = ½*(Speed of downstream – Speed of upstream)

= > (1/2)*2 = 1 km/hr

**2) Answer: c)**

Let the numbers be x, x+2, x+4, x+6, x+8 and x+10,

Then, (x + x+2 + x+4 + x+6 + x+8 + x+10) / 6 = 55

6x + 30 = 330

6x = 330 – 30

6x = 300

X = 300/6 = 50

Largest number = x+10 = 50 +10 = 60

**3) Answer: c)**

5 years ago, the ratio of age of A and B = 3 : 2 (3x, 2x)

The present age of A and B = 3x + 5, 2x + 5

Present age of C = Present age of A – 7

Present age of D = 20 – 6 = 14

Present age of C = 2 * present age of D

= > 2*14 = 28 years

Present age of A = 28 + 7 = 35 years

3x + 5 = 35

3x = 30

X = 10

The present age of B = 2x + 5 = 25 years

**4) Answer: d)**

Let the length and breadth of the rectangle is 10 cm and 10cm,

Previous area = 10*10= 100

New length = 10*(115/100) = 11.5

New breadth = 10*(85/100) = 8.5

New area = 11.5*8.5 = 97.75

Required percentage = [(100 – 97.75)/100]*100 = 2.25 % decreased

**5) Answer: d)**

The investment ratio of P, Q and R = 3: 6: 8

The initial investment of P = Rs. 42000

3’s = 42000

1’s = 14000

Initial investment of Q = Rs. 84000

Initial investment of R = Rs. 112000

The share of P, Q and R

= > [42000*12]: [84000*12]: [112000*6 + 56000*6]

= > 504000: 1008000: 1008000

= > 1: 2: 2

Total profit = Rs. 175000

5’s = 175000

1’s = 35000

The share of Q = 2’s = 2*35000 = Rs. 70000

**Direction (6-10) :**

**6) Answer: c)**

The annual salary of each IT employee in the year 2011 = 3.72 lakhs

The sum of the monthly salary of each marketing employee in the year 2011 and 2012 = Rs. 56500

The monthly salary of each marketing employee in the year 2011

= > 56500 – (342000/12)

= > 56500 – 28500 = Rs. 28000

The total monthly salary of each employee in all the given departments together in the year 2011

= > (264000/12) + 28000 + (288000/12) + (300000/12) + (372000/12)

= > 22000 + 28000 + 24000 + 25000 + 31000 = Rs. 130000

The sum of the annual salary of each Marketing and IT employees in the year 2015 = 7.98 lakhs

IT + Marketing = 798000 –à (1)

The annual salary of each marketing employees in the year 2015 = The annual salary of IT employees in the year 2015 – 42000

IT – Marketing = 42000 –à (2)

By solving the equation (1) and (2), we get,

IT = 4.2 lakhs, Marketing = 3.78 lakhs

The total monthly salary of each employee in all the given departments together in the year 2015

= > (318000/12) + (378000/12) + (348000/12) + (360000/12) + (420000/12)

= > 26500 + 31500 + 29000 + 30000 + 35000 = Rs. 152000

Required difference = 152000 – 130000 = Rs. 22000

**7) Answer: a)**

The annual salary of each marketing employees in the year 2014 = The annual salary of each Finance department employees in the year 2015

The annual salary of each marketing employees in the year 2014 = 3.6 lakhs

The average annual salary of each marketing employees in the year 2011 and 2015

= > 3.57 lakhs

The total annual salary of each marketing employees in the year 2011 and 2015

= > 3.57*2 = 7.14 lakhs

The average annual salary of each marketing employees in all the given years together

= > (7.14 + 3.42 + 3.48 + 3.6 + 3.84)/6

= > 21.48/6 = 3.58 lakhs

**8) Answer: d)**

The monthly salary of each Human resource development employees in the year 2015 and 2016 together = Rs. 58500

The monthly salary of each Human resource development employee in the year 2016 = > 58500 – (348000/12)

= > 58500 – 29000 = Rs. 29500

The annual salary of each Human resource development employee in the year 2016

= > 29500*12 = Rs. 354000

The total amount spent for the salaries of total employees in Human resource department in the year 2012 and 2016 together

= > (3.12*40) + (3.54*85)

= > 124.8 + 300.9 = 425.7 lakhs

**9) Answer: b)**

The monthly salary of each production department employee in the year 2012

= Rs. 24000

The annual salary of each production department employee in the year 2014 = Rs. 12000 + The annual salary of each production department employee in the year 2012

= 288000+12000 = 300000

So, the monthly salary of each production department employee in the year 2014 = 300000/12 = Rs. 25000

The total monthly salary of each production department employees in all the given years together

= > (264000/12) + 24000 + (294000/12) + 25000 + (318000/12) + (324000/12)

= > 22000 + 24000 + 24500 + 25000 + 26500 + 27000

= > Rs. 149000

The sum of the monthly salary of each IT employees in the year 2011 and 2013 together = Rs. 64000

The annual salary of each IT employee in the year 2015 = 4.2 lakhs

The salary of each IT employees in the year 2015 = 420000/12 = Rs. 35000

The total monthly salary of each IT employees in all the given years together

= > 64000 + (378000/12) + (402000/12) + 35000 + (426000/12)

= > 64000 + 31500 + 33500 + 35000 + 35500 = Rs. 199500

Required ratio = 149000: 199500 = 298: 399

**10) Answer: c)**

The monthly salary of each employee in production department in the year 2012 = > Rs. 24000

The annual salary of each employee in the year 2012 in all the given department together

= > (24000*12) + 342000 + 312000 + 318000 + 378000

= > 1638000 = 16.38 lakhs

The sum of annual salary of each employee in Marketing and IT department in the year 2015 = 7.98 lakhs

The annual salary of each employee in the year 2015 in all the given department together

= > 3.18 + 7.98 + 3.48 + 3.6 = 18.24 lakhs

Required % = (16.38/18.24)*100 = 90 %
