Answers & Solutions:

1) Answer (A)

Let total income = 360$x$

Expenditure on education = $\frac{70}{360} * 360x = 70x$

Expenditure on housing = $\frac{54}{360} * 360x = 54x$

=> Required difference = $70x – 54x$ = 1600

=> $x$ = 100

Expenditure on food = $\frac{120}{360} * 360x = 120x$

=> 120*100 = 12000

2) Answer (B)

Monthly income = 36,000

Monthly savings = $\frac{60}{360}$ * 36000 = 6,000

=> Yearly savings = 12*6000 = 72,000

3) Answer (A)

For a straight line to pass through origin, both of its x & y coordinates should be ‘0’.

(A) : 2x – 3y = 0

=> If x = y = 0, then L.H.S. = 0 = R.H.S

=> It passes through origin

(B) : x + 2y + 9 = 0

=> If x = y = 0, then L.H.S. = 9 $\neq$ R.H.S. = 0

=> It does not pass through origin

(C) : 5x – 4 = 0

=> If x = 0, then L.H.S. = -4 $\neq$ R.H.S. = 0

=> It does not pass through origin

(D) : 2y – 13 = 0

=> If y = 0, then L.H.S. = -13 $\neq$ R.H.S. = 0

=> It does not pass through origin

Ans – (A)

4) Answer (A)

Runs scored in 1st and 2nd innings respectively :

Dhoni = 60+80 = 140 [MAX]

Virat = 50+50 = 100

Pujara = 70+10 = 80

Dhawan = 30+20 = 50

Since, Dhoni scored the maximum in both innings

=> Average = 140/2 = 70

5) Answer (C)

No. of students who like football = 15

Total students = 60

Angle used for football = $\frac{15}{60}$ * 360 = 90°

6) Answer (D)

Sales of cool sip in :

1988 – 25

1989 – 6 [MIN]

1990 – 19

1991 – 15

1992 – 25

1993 – 30

=> Sales of cool sip is minimum in 1989

Ans – (D)

7) Answer (A)

Sales of cool sip from 1988 to 1993 = 25+6+19+15+25+30 = 120

=> Average sales = 120/6 = 20

Sales of pep up = 30+35+30+25+20+20 = 160

=> Average sales = 160/6 = 26.67 [MAX]

Sales of dew drop = 10+15+25+15+30+25 = 120

=> Average sales = 120/6 = 20

Average sales of pep up is maximum

8) Answer (B)

Sales of pep up in 1989 = 35

Sales of pep up in 1990 = 30

=> % decrease = $\frac{35-30}{35}$ * 100 = 14.28%

= ~14%

9) Answer (B)

Sales of cool sip in 1989 = 6

Sales of cool sip in 1990 = 19

=> % increase = $\frac{19-6}{6} * 100 = 216.67\%$

= ~217%

10) Answer (B)

Sales of dew drop in :

1988 – 10

1989 – 15

1990 – 25

1991 – 15

1992 – 30 [MAX]

1993 – 25

=> Sales of dew drop is maximum is 1992

11) Answer (D)

Sales of cool sip from 1988 to 1993 = 25+6+19+15+25+30 = 120

=> Average sales = 120/6 = 20

Sales of pep up = 30+35+30+25+20+20 = 160

=> Average sales = 160/6 = 26.67

Sales of dew drop = 10+15+25+15+30+25 = 120

=> Average sales = 120/6 = 20

Average sales of both cool sip and dew drop is minimum.

12) Answer (C)

Total no. of people in South zone = 1450+1120+420+350+50 = 3390

People who take coffee at least once a day = (1 to 3 times a day) + (more than 3 times a day)

= 1450+1120 = 2570

=> Required % = $\frac{2570}{3390}$ * 100

= 75.81%

13) Answer (D)

Total no. of people in :

North zone = 410+1220+1640+620+950 = 4840

East zone = 310+830+710+540+430 = 2820

South zone = 1450+1120+420+350+50 = 2570

=> Total no. of people in non-west zone = 4840+2820+2570 = 11050

No. of people who take coffee only once a week in non-west zone = 620+540+350 = 1510

=> Required % = $\frac{1540}{11050}$ * 100 = 13.67%

= ~14%

14) Answer (B)

No. of people who take coffee more than 3 times a day = 410+310+700+1450 = 2870

No. of people who never take coffee = 950+430+620+50 = 2050

=> Required ratio = $\frac{2870}{2050}$ = 1.4

=> 1.4 : 1

15) Answer (A)

Profit = Income – Expenditure

Income in 2007 = 45

Expenditure in 2007 = 40

=> Profit in 2007 = 45-40 = 5

Income in 2008 = 60

Expenditure in 2008 = 50

=> Profit in 2008 = 60-50 = 10

Required difference = 10-5 = 5

16) Answer (C)

Expenditure of the company in :

2005 = 25

2006 = 40

2007 = 40

2008 = 50

2009 = 55

=> Average expenditure = $\frac{25+40+40+50+55}{5}$ = 42

So, only in years ‘2008’ & ‘2009’, the expenditure of the company is greater than the average expenditure.

Ans – (C)

17) Answer (C)

Income of company in 2007 = 45

Income of company in 2008 = 60

=> % increase = $\frac{60-45}{45}$ * 100 = $\frac{100}{3}$

= 33$\frac{1}{3}$%

18) Answer (B)

Total income of the company over the years = 35+50+45+60+60 = 250

Total expenditure = 25+40+40+50+55 = 210

=> Required ratio = $\frac{250}{210}$ = 25 : 21

19) Answer (D)

The categories of qualitative variables are represented by bars where the height of each bar may be class frequency, class percentage and class relative frequency.

20) Answer (C)

No. of girls who ate fewer than 2 servings a day = (No. of girls who ate 0) + (No. of girls who ate 1)

= 15 + 10 = 25
