5.Answer c

The difference of difference is, 5, 10, 15, 20, 25,..

The answer is, 1030

Directions (Q. 6 – 10):

6.Answer b

 (32/100)*650 = x + (1125/25)

208 – 45 = x

X = 163

7.Answer a

10 ¼ + 9 ¾ – 4 3/8 – 12 7/8 = x

X = (10 + 9 – 4 – 12) (1/4 + ¾ – 3/8 – 7/8)

X = 3 (-2/8) = 3(-1/4)

X = (12 – 1)/4 = 11/4 = 2 3/4

8.Answer d

(?*100)/(82 × 5 – 250) = 120 + 352

(x/160)*100 = 1345

X = 1345*(160/100)

X = 2152

9.Answer a

 (552*18*18)/12 = 156 + x

14904 = 156 + x

X = 14904 – 156

X = 14748

10.Answer c

 (7/12)*1632 + 361 = (25/100)*x

952 + 361 = (x/4)

X = 1313*4 = 5252

11.Answer b

The difference between simple interest and compound interest on certain time for 2 years is,

= > Diff = Sum*(r/100)2

= > Diff = 35000*(6/100)2

= > Diff = 35000*(3/50)2

= > Diff = 35000*(9/2500) = Rs. 126

12.Answer a

Present age of A and B is in the ratio = 5: 8 (5x, 8x)

After 5 years, the ratio will be = 2: 3

(5x +5)/(8x+5) = 2/3

15x + 15 = 16x + 10

X = 5

Present ages are, 40 and 25

The difference = 40 – 25 = 15

13.Answer c

The share of A, B and C = [36000*12]: [54000*12]: [48000*8]

= > 432000: 648000: 384000

= > 18: 27: 16

The difference between C’s share and A’s share in the annual profit was 400,

(18’s – 16’s) = 4000

2’s = 4000

1’s = 2000

Total profit = 61’s = 61*2000 = Rs. 122000

75 % of total profit = 122000*(75/100) = Rs. 91500

14.Answer b

Decreased weight = 8*2 = 16 kg

Weight of a new man = 75 – 16 = 59 kg

15.Answer d

A can do the work in,

= > (1/3)*work = 5

= > Whole work = 15 days

B can do the work in,

= > (2/5)*work = 10

= > Whole work = 25 days

(A + B)’s one day work = (1/15) + (1/25) = 40/(15*25) = 8/75

(A + B) can do the work in, 75/8 = 9 3/8 days

Directions (Q. 16 – 20)

16.Answer b

The central angle of shop B

= > (20/100)*360 = 720

17.Answer a

Total vegetarian burgers in shop A

= > 1000*(10/100)*(45/100) = 45

Total vegetarian burgers in shop D

= > 1000*(18/100)*(30/100) = 54

Required difference = 54 – 45 = 9

18.Answer a

Total number of non vegetarian burgers in shop E

= > 1000*(15/100)*(3/5)

= > 90

19.Answer d

The average number of burgers in the shop A, B and C together

= > [(10 + 20 + 15)/100]*(1000/3)

= > 150

20.Answer b

Required % = (22/18)*100 = 122 %
