Answers:

Directions (Q. 1-5):

1). Answer b

Explanation:

? = [ (12.8×88 -16.4×55.5) × 100 ] / 10

= (1126.4 – 910.2) × 10 = 216.2 × 10

= 2162

2). Answer d

Explanation:

[ (13)3]2/3 ÷ [(13)4]3/4 × ? = (√13)5

Or, 132 ÷ 133 × ? = (√13)5

Or, 13-1 × ? = (√13)5

Or, ? = 13 ×(√13)5 = (√13)7

3). Answer e

Explanation:

? = 7√11 × 16√11 – 784

= 1232 – 784 = 448

4). Answer e

Explanation:

? = (385/47) × (517/56) × (84/11) × (9/22) – (33/5)

= (385×27)/44 – (33/5) = (51975 – 1452) / 220

= 50523/220 = 229.65

5).Answer b

Explanation:

? = 1739÷ 47 + 2679 ÷ 57 + 3819 ÷ 67 + 5159 ÷ 77 + 6699 ÷ 87 + 1245 ÷ 83

= 37 + 47 + 57 + 67 + 77 + 15 = 300

 

Directions (Q. 6-10):

6). Answer d

Explanation:

The series is

7). Answer d

or, +18, +22,+26, +30, +34,

The series is

Directions (Q. 11-15):

  1. Answer c

Explanation:

Number of candidates failed in the Exam from Karnataka and Rajasthan together

= 170250 + 74000 = 244250

Number of candidates failed in the exam from Gujarat and Maharashtra together

= 37500 + 117750 = 155250

Required ratio

= 244250 : 155250

= 977 : 621

  1. Answer e

Explanation:

The number of candidates passed from Rajasthan and Assam together

= 111000 + 48000 = 159000

Total number of failed candidates from Karnataka = 170250

Required percentage

= (159000/170250) × 100

= 93.39%

  1. Answer b

Explanation:

The number of candidates appearing for the exam from Assam and Gujarat together

= 108000 + 125000 = 233000

Total number of candidates appearing for the exam from Maharashtra and Uttar Pradesh together

= 314000 + 273000 = 587000

Required percentage

= 233000/587000 × 100

= 39.69

= 40%

  1. Answer a

Explanation:

Total number of candidates appearing from all the states together

= (125000 + 314000 + 108000 + 227000 + 185000 + 273000)

= 1232000

Required percentage

= 159250/1232000 × 100

= 12.93

  1. Answer d

Explanation:

State has the highest number of passing students is Maharashtra = 196250

State has the lowest number of students failed is Gujarat = 37500

Difference = 196250 – 37500

= 158750

  1. Answer c

Explanation:

The average age = 25

∴ the total age = 25 × 3 = 75

Hence, the age of the eldest boy = 6/15 × 75 = 30

  1. Answer d

Explanation:

The ratio of the 50p, 25p,10p coins be 5x,3x,2x

(5x + 3x + 2x) = 276

(5x/2 + 3x/4 + 2x/10) = 276

(50x + 15x + 4x) /20 = 276

∴ x = 80

Hence the numbers of coins are,

50p = 5 × 80 = 400

25p = 3 × 80 = 240

10p = 2 × 80 = 160

Hence the answer is (400,240,160)

  1. Answer b

Explanation:

Volume of the cylinder = (22/7)×r^2h

Ratio of two cylinders = (22/7)× (4)^2 × 3 :(22/7)× (7)^2 × 8

= 4 × 4 × 3 : 7 × 7 × 8 = 6 : 49

  1. Answer a

Explanation:

A : B : C = 5 : 3 : 2

A = 5/10 × 5000 = 2500

B = 3/10 × 5000 = 1500

C = 2/10 × 5000 = 1000

If the amount Rs.600 is added to each of their shares then the new share becomes,

3100 : 2100 : 1600 = 31 : 21 : 16

20) Answer b

Explanation:

Let the cost price of article = Rs. x

According to question,

x * 92/100 =1380

x = Rs.1,500/-

Required price = 1500 * 108/100

= Rs.1620

(or)

Shortcut method:

S.P1 / (100-loss%) = S.P2 /(100+Profit%)

1380/92 = S.P2 / 108

S.P2 = 1620
