Directions (1-5) :

The pattern is as follows:

6 * 9 + 1=55

7 * 10 + 2 = 72

8 * 11 + 3=91

9 * 12 + 4 = 112

10 * 13+ 5= 135

11 * 14 +6 = 160

The pattern is as follows:

8 * 4 + 12=33

9 * 5 + 22=49

10 * 6+ 32=69

11 * 7+ 42=93

12 * 8+ 52=121

13 * 9+ 62=153

The pattern is as follows:

7 * 1 + 0.5 = 7.5

7.5 * 2 + 1.5 = 16.5

16.5 * 3 + 2.5 = 52.0

52.0 * 4 + 3.5 = 211.5

211.5 * 5 + 4.5 = 1062.0

The pattern is as follows:

1672 – 22 + 1 = 1669

1669 – 32 + 1 = 1661

1661 – 42 + 1 = 1646

1646 – 52 + 1 = 1622

1622 – 62 + 1 = 1587

The pattern is as follows:

26 + 12 = 38

38 + 12 + 14 = 64

64 + 12 + 14 + 16 = 106

106 + 12 + 14 + 16 + 18 = 166

166 + 12 + 14 + 16 + 18 + 20 = 246

Directions (6-10) :

Milk=9/20 * 240=108

Water=11/20 * 240=132

Total quantity =240+120=360

Required percentage=132/360*100=36.66%

Efficiency ratio  A/B =4/5

Time ratio A/B = 5/4

1/5x + 1/4x = 1/20

9/20x = 1/20

x=9 days

1/45+1/36+1/C=1/15

1/C=1/15-1/45-1/36

1/C=(36-12-15)/540=1/60

C can complete the work in 60 days

Odd number=(1, 3, 5, 7, 9, 11, 13, 15, 17, 19)

Required probability=10/20=1/2

Let the shopkeeper bought=100x pens

CP=126/18 * 100x=Rs.700x

SP=216/24 * 100x=Rs.900x

Profit=900x-700x=Rs.200x

100x/200x * 130 = 65

Profit ratio=(4x*6 + 4x* (125/100) *6 ):(5x*6 + 5x* (120/100) *6)

=(24x+30x):(30x+36x)

=54:66=9:11

Total profit=20/11*2200=4000

80x=1600000

x=20000

C=48000-20000=28000
