1. 3 : 4
2. 4 : 3
3. 3 : 7

5. 7:2

Directions (Q. 1 – 5):

The pattern is, *0.5 -1, *1 -1, *1.5 -1, *2 -1, *2.5 -1…

The pattern is, ÷ 11, ÷ 8, ÷ 5, ÷ 2,..

The pattern is, +(23 – 22), +(33 – 32), +(43 – 42), +(53 – 52), +(63 – 62),..

The difference of difference is, -22, +32, -42, +52….

The pattern is, *3 – 5, *3 – 10, *3 – 15, *3 – 20, *3 – 25….

Directions (Q. 6-10):

(2 + 3 – 5 + 4)(¼ + 7/8 – ¾ + 1/2) = x

4 (7/8) = x

X = 4 7/8

[56/(8*8)]*512 + 289 = x

X = 448 + 289

X = 737

(5/9)*(7/2)*(8/3)*(152/100)*2700 = x

X =21280

2052 / (82 – x) = 57

(2052/57) = 82 – x

82 – x = 36

X = 82 – 36 = 46

3x = (3)6 × (3)3 ÷ 37 × 310

3x = 36+3-7+10

3x = 312

X = 9

5 years hence, Anitha: Bhuvana = 4: 5(4x, 5x)

5 years ago, the age of Anitha is equal to the age of Bhuvana, 10 years ago

= > (4x – 10) = (5x – 15)

= > x = 5

The present age of Anitha = 4x – 5 = 15 years

Total probability = 11C2

Required probability = 2C2 or 4C2

The probability that the marbles are either red or pink,

= > 2C2 or 4C2 / 11C2

= > 7/55

Savings = 30 %

Expenditure = 70 %

According to the question,

= > (80/100)*expenditure = 3500

Expenditure = 4375

(70/100)*monthly salary = 4375

Monthly salary = 6250

Savings = 30 % of monthly salary = (30/100)*6250

= > 1875

Let the C.P be x,

M.P = 2400 + C.P = 2400 + x

S.P = (2400+x) – 300 = 2100 + x

S.P = (120/100)x =(6/5)x

2100 + x = (6/5)x

10500 + 5x = 6x

C.P(X) = 10500

To earn a profit of 35 %,

S.P = (135/100)*10500 = Rs. 14175

Let the two numbers be x and y,

X – Y = 1180

(45/100)X = (36/100)Y

(X/Y) = 4/5

1’s = 1180

The two numbers be,

= > 4’s = (1180*4) = 4720

= > 5’s = (1180*5) = 5900

Directions (Q. 16 – 20):

Number of employees retired from finance dept in the years 2012, 2013 and 2014

= (29+54+42) =125

Number of employees retired from marketing dept in the year 2014 = 64

Required difference = (125 – 64) = 61

Total number of soldiers retired from IT over all the years together.

= (16 + 19 + 24 + 18 + 15 + 45) = 137

Number of employees retired from Manufacturing in the years 2011 and 2012

= (37+52) = 89

Required percentage = (89/137) x 100 = 65%

Required average

= (54+72+28+27+54)/5

= 225/5

= 45

It is obvious from the table.

In no department, the number of employees retired continuously increased from the year 2010 to 2015

The number of employees retired from marketing dept in 2013 = 72

The number of employees retired from HR dept in the year 2014 = 54

Required ratio = 72: 54 = 4: 3
