Number -> opposite letter of first and last letter and addition of those positions

Symbols -> count the no. of letters in the word

For,

2 letter -> @

3 letters -> #

4 -> $

5 -> %

6-?

8 -> &

9 -> *

11 -> ~

Letter -> count the no. of letters in the word and position of reverse alphabet.

Example

N E W -> 17 # ×

1. Opposite of N is m => m’s position -> 13

Opposite of w is D => D’s position -> 4

Add the (M, D) position = 13 + 4 = 17

2. no. of letter 3 so, the symbol #

3. no. of letter 3 reverse alphabetical order 3 position is x

Devotees Number of devotees Male devotees Female devotees
Home 900000 252000 648000
Factories 300000 156000 144000
Offices 450000 180000 270000
Hospitals 750000 525000 225000
Marketplace 600000 360000 240000

Q.1) d

Required percentage [(648000/90000)×100] = 72%

Q.2) 

Required total = 648000+144000+270000+225000+240000= 1527000

Q.3) a

Required percentage =

Q.4) c

Required total = 681000

Q.5) b

Required ratio = 252000: 240000 = 63: 60 = 21: 20


(Q.6 – 10)

Cost price Cost price (in. Rs) Selling price (in. Rs) Marked price (in. Rs)
2012 990 1188 1300
2013 1089 1200 1500
2014 1197.9 1300 2000
2015 1317.69 1400 2000

 

Q.6) b

Required total = 1300+1500+2000+2000 = 6800

Q.7) a

Required percentage =

Q.8) d

The discount on a Ganesh idol in the year 2012 = 1300-1188 = 112

Profit of a Ganesh idol in the year 2013 = 1200- 1089 = 111

Required ratio = 112: 111


Q.9) b

Required percentage =


Q.10) c

Required total profit = 111×350 = 38850


Q.11) b

Boat E,

Downstream distance = 30% of 1200 = 360 km

Upstream distance = 30% of 800 = 240 km

Let rate of Boat E be a and Rate of stream be b

From the ratio,

a+ b= 6x

a-b = 4x

X= 10

Required rate of stream, b=km/hr


Q.12) c

Boat B,

50% of distance along the current in 3/2 hours

100% of distance along the current in hours

Downstream speed = 180÷3 = 60 km/hr

From the ratio,

2x+ x = 60

X= 20 km/hr

Upstream speed = 2x-x=x=20km/hr

Required time  (180/60)+(160/20) = 11 hrs

Boat D,

75% of distance against the current in 3 hours

100% of distance against the current in 3×100/75 = 4 hours

Upstream speed 200/4 = 50 km/hr

From the ratio,

11x- x = 50

X = 5 km/hr

Downstream speed of Boat D =12×5 = 60 km/hr

Required time   (120/60)+ (200/50) =  6 hours

Required difference = 11-6= 5 hours


Q.13) d

Boat A,

x = 20 km/hr

Speed of boat A in still water =3x= 60 km/hr

Boat C,

x = 5 km/hr

Speed of boat C in still water =9x= 45 km/hr

Required total = 60+45 =105 km/hr


Q.14) c

Boat B,

1/4th distance of upstream is ¼ × 160 = 40 km

Boat B travels 40km upstream in 2 hours

Upstream speed 

From the ratio,

2x-x = 20

X = 20 km/hr

Therefore, rate of stream on which Boat B travels= x= 20 km/hr


Q.15) c

Boat C,

x = 5 km/hr

Therefore, downstream speed of boat C is 50 km/hr.

Boat D,

Upstream speed of boat D is 50 km/hr

From the ratio,

11x-x= 50

X= 5

Downstream Speed of boat D is 11x+x=12x = 60 km/hr

Required time,

.


Q.16) e

Surface area of cube= 6a2=294

Side= radius= 7cm

H=14cm

CSA of cylinder= 2πrh= 2×22/7×14×7=616cm2


Q.17) d

r=3.5m


Q.18) b

If Raja runs 200m then Vijay will run  (450÷500)×200) = 180

When Vijay runs 300m then Chitranjan runs (270÷300)×180) = 162

When Vijay runs 180m then Chitranjan will run 

Raja beats Chitranjan by (200-162) = 38 m


Q.19) d


Q.20) b

Take 1 as unit digit then other digits can be arranged in 2! =2 ways

So sum of unit digit of all possible numbers= 2×1+2×3+2×5=18

Similarly, the sum of the digits at the ten’s place, hundred’s place will be 18

So, the sum of all numbers = 18(1 + 10 +100) = 1998


Q.21) a

Vowels= EAO

Remaining= SYWRD


Q.22) d

So


Q.23) d

 

(A+B)’s one min output =

Whole tank will be filled in 60 min

So 1/3 of the tank will be filled in 20 min


Q.24) c

P=5000
