Answers :

1) Answer: B

Required ratio = 3600:(12000 – 7200)

= 3:4


2) Answer: C

Number of accounts in Indian bank = 5/4 * 14400 = 18000

Number of current accounts in Indian bank = 10800 – 3600 = 7200

Number of saving accounts in Indian bank = 18000 – 7200 = 10800


3) Answer: A

Number of current accounts in SBI = 12000 – 7200 = 4800

Number of current accounts in IOB = 14400 – 9000 = 5400

Number of current accounts in BOB = 9600 – 3600 = 6000

Number of current accounts in BOM = (4800 + 5400 + 6000)/3 = 5400

Number of saving accounts in BOM = 5/4 * 5400 = 6750


4) Answer: D

Number of current accounts in IOB = 14400 – 9000 = 5400

Required difference = 7200 – 5400 = 1800


5) Answer: E

Required total = 3600+ (10800 – 3600) * 50/100 + 3600 * 80/100 + (9600 – 3600)

= 16080


6) Answer: B

Expenditure of F = 125/100 * (18000 – 6000) = 15000

4x – x = 15000

x = 5000

Savings of F = 5000

 

7) Answer: D

Expenditure of G = (30000 – 10000) – (15000 – 5000)

= Rs.10000

Income = 6/5 * 10000 = 12000

Savings = 1/6 * 12000 = 2000

House rent = 10000 * 65/100 * 60/100 = 3900

Difference = 3900 – 2000 = Rs.1900


8) Answer: C

E spend household and education fee = 75/100 * (35000 – 12000) = 17250

Household = 13/2 education fees

Education fees = 2k/15k * 17250 = 2300

Required answer = 2300 * 12 = Rs.27600


9) Answer: A

Expenditure of F = 17/13 * (27500 – 8000) = 25500

Savings of F = 6000 + 5000 = 11000

Income of F = 25500 + 11000 = Rs.36500


10) Answer: C

Expenditure of A = 18000 – 6000 = 12000

Expenditure of C = 27500 – 8000 = 19500

Expenditure of D = 30000 – 10000 = 20000

Expenditure of E = 35000 – 12000 = 23000

Required average = (12000 + 19500 + 20000 + 23000)/4

= 18625

Answers :

11) Answer: A

Number of boys like Maths = 45 * 60/100 = 27

Number of boys like Physics = 33 * 200/300 = 22

Number of boys like Chemistry = 43 – 43 = 0

Required total = 27 + 22 = 49


12) Answer: B

Required difference = (42 + 34) – (30 + 32)

= 76 – 62

= 14


13) Answer: D

Required percentage = (48 + 33 + 35)/(36 + 32 + 37) * 100

= (116/105) * 100

= 110.47%


14) Answer: C

Required average = (44 + 43 + 36 + 30 + 32)/5

= 185/5

= 37


15) Answer: B

Number of girls in D = 4/5 * (36 + 38 + 31) = (105/5) * 4 = 84

Number of girls in F = 7/10 * (37 + 41 + 32) = (110/10) * 7= 77

Difference = 84 – 77 = 7


16) Answer: B

= 1:1


17) Answer: D

= 5:4

Total number of students = 9/1 * 6 = 54


18) Answer: E

Average weight of the class = 24 * 400/300 = 32

= 2:1

Number of girls = 1/2 * 12 = 6

Total weight of girls = 6 * 24 = 144 kg


19) Answer: A

Number of boys = 8

Number of girls = 2 * 8 = 16

Average weight of the class = (8 * 42 + 36 * 16)/24

= (336 + 576)/24

= 912/24

= 38 kg


20) Answer: E

Number of boys = x

Number of girls = y

We can’t find the number of boys and girls.

So,We cannot find the answer.

Answers :

Directions (21-25) :

For Company A,

Number of Manual Pen Tablets = 960

Percentage of digital Tablets = 40%

Percentage of Manual Tablets = 60%

Total number of Pen tablets = 960/60 x 100 = 1600

Number of Digital tablets = 40% of 1600 = 640

Now we can calculate the data for all companies


21) Answer: C

Revenue generated by Company C from manual tablets = 600 x 180 = 108000

Revenue generated by Company C from digital tablets = 216000

Total revenue = 108000 + 216000 = Rs. 324000


22) Answer: B

Total number of manual tablets by (A + C + D) = 960 + 600 + 480 = 2040

200% of total number of digital tablets by (B + E) = 2 x (1320 + 1056) = 2 x2376 = 4752

Required % change = (4752 – 2040)/4752 x 100 = 57% approx.


23) Answer: A

Number of manual pen tablets sold by company F = 62.5% of 1056 = 660

Total number of pen tablets sold by company F = 3 x 480 = 1440

Number of digital pen tablets sold by company F = 1440 – 660 = 780


24) Answer: E

Total number of manual pen tablets manufactured by (B + C) = (1080 + 600)/75 x 100 = 2240

Total number of Digital pen tablets manufactured by (B + C) = (1320 + 900)/80 x 100 = 2775

Total number of tablets manufactured = 2240 + 2775 = 5015


25) Answer: D

Average number of digital pen tablets = (640 + 1320 + 900 + 520 + 1056)/5 = 887.2

Average number of manual pen tablets = (960 + 1080 + 600 + 480 + 1144)/5 = 852.8

Required difference = 34.4


Directions (26-30) :

The given line chart can be rewritten as,


26) Answer: B

Number of female votes casted as valid = (5/12) (5880)=2450

Total invalid votes casted by females = 3600-2450 = 1150

Total valid votes casted by Males = 5880 – 2450 = 3430

Total invalid votes casted by Males = 4800 – 3430 = 1370

Required difference = 1370 – 1150 = 220


27) Answer: A

Total invalid votes casted in city P = 8400 – 5880 = 2520

Total invalid votes casted in city Q = 6600 – 3300 = 3300

Total invalid votes casted in city R = 4500 – 3600 = 900

Total invalid votes casted in city S = 7200 – 3960 = 3240

Total invalid votes casted in city T = 5000 – 3000 = 2000

Therefore,

Number of invalid votes casted in city Q is high.


28) Answer: E

Total invalid votes casted by females =65% of 3000 =1950

Total valid votes casted by females = (100-65)% of 3000 = 1050

Total valid votes casted by males = 3000-1050 =1950

Total invalid votes casted by males = 2000- 1950 =50


29) Answer: C

Required ratio

=3300: 3960
