Directions (Q. 6 – 10):

6). Answer a

2160 ÷ 16 + 3318 ÷ 21 + 3234 ÷ 7 = (x) % of 800

(2160/16) + (3318/21) + (3234/7) = (x/100)*800

135 + 158 + 462 = 8x

755 = 8x

X = (755/8) = 94.375

7). Answer c

(72/100)*11350 + (48/100)*750 – (4/9)*927 = x

8172 + 360 – 412 = x

X = 8120

8). Answer b

6 ¾ – 7 5/8 + 9 ½ – 3 1/8 + 1 ¾ = x

(6 – 7 + 9 -3 +1) (3/4 – 5/8 + ½ – 1/8 + ¾) = x

6 [(6 – 5 + 4 – 1 + 6)/8] = x

X = 6 (10/8) = 6 (5/4) = 7 (1/4)

9). Answer d

[(96/6)*16*16] + 152 = x + (15876/14)

4096 + 152 = x + 1134

X = 4096 + 152 – 1134

X = 3114

10). Answer c

(4/5)*11325 + (56/100)*1750 = x2 + 436

9060 + 980 – 436 = x2

10040 – 436 = x2

9604 = x2

X = 98

 

11). Answer b

The share of A, B and C

= > [75000*4 + 83000*8]: [65000*12]: [55000*4 + 49000*8]

= > 964000: 780000: 612000

= > 241: 195: 153

Total profit = Rs. 21204

589’s = 21204

1’s = 36

The share of B = 195*36 = Rs. 7020

12). Answer a

C.I annually:

56000*(6/100) = 3360

C.I half yearly:

56000*(3/100) = 1680

57680*(3/100) = 1730.4

C.I = 1680 + 1730.4 = 3410.4

Required difference = 3410.4 – 3360 = Rs. 50.40

13). Answer d

Let the speed of the boat in still water be x km/hr

Speed of the current= x/4

Downstream speed = x + x/4= 5x/4

Downstream speed in km/hr = 16*60/28= 30 km/hr

So,

5x/4= 30

x = 24 km/hr

Distance in 20 minutes= 24*20/60= 8 km

14). Answer c

Relative speed = (50 + x) km/hr = (50 + x)*(5/18) m/s

T = D/S

9 = (150+180) / [(50 + x)*(5/18)]

132 = 50 + x

X = 132 – 50

X = 82 km/hr

15). Answer a

Total ages of 6 family members 3 years ago

= 6*40= 240 years

Total ages of the family at present including daughter

= 240+18= 258

Total ages of the family including daughter- in-law

= 39*6

= 234 years

So,

Required difference= 258-234= 24 years.

Directions (Q. 16 – 20)

16). Answer d

Total number of students enrolled for the membership in library A in the years 2012, 2014 and 2016 together

= > 420 + 280 + 370 = 1070

Total number of students enrolled for the membership in library B in the years 2011, 2013 and 2015 together

= > 280 + 450 + 260 = 990

Required % = (1070/990)*100 = 108.08 % = 108 %

17). Answer a

The total number of students enrolled for the membership in library B in all the given years together

= > 280 + 390 + 450 + 580 + 260 + 610

= > 2570

18). Answer c

The total number of students enrolled for the membership in library A

= > 350 + 420 + 560 + 280 + 480 + 370

= > 2460

The total number of students enrolled for the membership in library B

= > 280 + 390 + 450 + 580 + 260 + 610

= > 2570

Required difference = 2570 – 2460 = 110

19). Answer b

The total number of students enrolled for the membership from both libraries A and B together in the year 2017

= > (370 + 610)*(125/100)

= > 1225

20). Answer b

The total number of students enrolled for the membership in library A in the year 2011, 2014 and 2016 together

= > 350 + 280 + 370 = 1000

The total number of students enrolled for the membership in library B in the year 2012, 2013 and 2015 together

= > 390 + 450 + 260 = 1100

Required ratio = 1000: 1100 = 10: 11
