**Answers:**

**Directions (1-5): **

**Answer: d**

**Solution:**

Let the income of the companies X and Y in 2007 be Rs x.

Also Let us take the expenditure of the company X be E_{1 }and that of the company Y be E_{2}.

Now, 20= [(x- E_{1})/ E_{1}]*100

x=120 E_{1}/100………….. (1)

Also for company Y,

10 = [(x- E_{2})/ E_{2}]*100

x= 110 E_{2}/100………….. (2)

From (1) and (2), we have

120 E_{1}/100=110 E_{2}/100

E_{1/} E_{2}= 110/120

=11/12

Hence E_{1}: E_{2}= 11:12

**Answer: e**

**Solution:**

Given that the income of company Y in 2006= Rs 63 lakhs and profit percentage= 50%

Let Rs x be the expenditure of the company Y in 2006.

Then, 50= [(63-x)/x]*100

x = (63-x)*2

3x= 126

x=Rs 42 lakhs

Then in 2008, the expenditure of the company Y= Rs 21 lakhs

Let y be the income of the company Y in 2008.

Then, 30 = [(y-21)/21]*100

63= 10y-210

y= Rs 27.3 lakhs

**Answer: a**

**Solution:**

Let x be the expenditure of the company X in 2010.

Given that, the profit of company X in 2010= Rs 67.5 lakhs

(i.e) 22.5/100*x=67.5

x= Rs 300 lakhs

Then the expenditure of the company X in 2011= Rs 200 crores

Now, profit of the company X in 2011= 200*10/100

= Rs 20 lakhs

**Answer: e**

**Solution:**

Since we cannot find the income of a company Y for all the years separately, the total expenditure of the same company will not be determined.

**Answer: e**

**Solution:**

Given that, Income_{2008}/ Income_{2011}= 5/7

Since the profit percentage of a company X in 2008 is 35% and that of in 2011 is 10%, we have

135% of Expenditure_{2008}/110 % of Expenditure _{2011}= 5/7

(i.e) Expenditure_{2008}/ Expenditure _{2011}= 5/7*110/135

= 110/189

**Answer: e**

**Solution:**

Let the ages of Manu and Salim 15 years ago be 2x and 5x respectively.

Then, the present age of Manu= (2x+15)

And the present age of Salim= (5x+15)

Now, (2x+15+5)/ (5x+15+5) =3/5

(2x+20)/(5x+20)=3/5

5(2x+20) =3(5x+20)

x=8

Thus present age of Manu= (2x+15) =31

Present age of Salim= (5x+15) =55

Required ratio= 31:55

**Answer: d**

**Solution:**

We know that surface area of the sphere= 4πr^{2}.

= 4*22/7*35*35

=15400 m^{2}

Then the cost of covering the spherical bowl= (15400*1.5) = Rs 23100

**Answer: c**

**Solution:**

Let the price of LG TV in the last year be 4x and the price of Samsung TV in the last year be 3x.

Then, (4x-10000)/(3x*120/100)=5/6

6(4x-10000) =5(3x*6/5)

6x= 60000

x= 10000

Thus the price of LG TV in the last year =4x= Rs 40000

**Answer: c**

**Solution:**

Let the rate of upstream be x km/hr and then rate of downstream be 3x km/hr.

Then, 2x= 28

x= 14 km/hr

(i.e) Rate of upstream= 14 km/hr

And rate of downstream= 42 km/hr

Thus, Rate of stream= ½(42-14)=1/2 *(28)= 14 km/hr

**Answer: a**

**Solution:**

Given that profit= Cost price of 50 pens

Now, Total profit= Selling price of 400 pens- Cost price of 400 pens

Cost price of 50 pens = 3825 – Cost price of 400 pens

Cost price of 50 pens+ Cost price of 400 pens=3825

Cost price of 450 pen =3825

Thus, Cost price of 1 pen= 3825/450= Rs 8.5

**Directions (11-15): **

- Answer: A

Sol:

15.6+0.7 =16.3

16.3+1.4 =17.7

17.7+2.1=19.8

19.8+2.8= 22.6

22.6+3.5= 26.1

- Answer : C

Sol:

750/2 *3 =1125

1125/3 *4 = 1500

1500/4*5 = 1875

1875/5*6 = 2250

2250/6*7 =**2625**
