1) S.I = (1 / 16) P

(1 / 16) P = (P × r × r) / 100 (Here n=r)

1 / 16 = r2 / 100

r2 =100/16

r = 10 / 4 = 2 ½ %

Let the speed of boat be x km/hr

According to the question, 10/(x – 4) + 10/(x + 4) = 80/60

=> 10 (x + 4 + x – 4) = 4/3(x2 – 16)

=> 15x = x2 – 16

=>x2 – 16 – 15x = 0

=> x = 16, -1

Therefore, the speed of boat in still water = 16km/hr

Reduction % in consumption

= [r/ (100 + r) x 100] %

= [25/ (100 + 25) x 100]

= 20%

Total probability= 12C4

Required probability= 1- none is from Tamil Nadu

= > 7C4

Required probability= 1- none is from Tamil Nadu

= > 1 – (7C4 / 12C4)

= > 1 – (7/99)

= > 92/99

Direction (Q. 6-10):

The pattern is, + (12 × 1), + (22 × 2), + (32 × 3), + (42 × 4), + (52 × 5)…

The pattern is, ÷6 +1, ÷5 +3, ÷4+5, ÷3 + 7, ÷2 +9, ÷1 + 11

The pattern is, *0.5 +0.5, *1 +1, *1.5 +1.5, *2 +2, *2.5+2.5….

The difference of difference is, 32, 52, 72, 92….

The pattern is, *6 -5, *5 -6, *4 -7, *3 -8,..

Directions (Q. 11 – 15):

13873 + (133/100) * 1600 – (7/5) * 4575 = x

X = 13873 +2128 – 6405

X = 9596

X= 9600(approx)

5537 + 143 × 6 – 77 × 13 + (10/100) × 1200 = x

X= 5537 + 858 – 1001 + 120

X = 5514 = 5520(approx)

6500 + 3601 × 15 – 8720 =x

X = 6500 + 54015 – 8790

X = 51725

(5/7) × 7007 + (6/9) × 864 – (23/7) × 1764 = x- 526

X = 5005 + 576 – 5796 + 526

X = 311

32 x3 + 289 + 601 = 1800

32 x3 = 1800 – 890

32 x3 = 910

X3 = 910/32 = 28

X= 3(approx)

Directions (Q. 16 – 20):

Required % = ([135/6]/[200/6]) x 100 = 67.5%

Let the expenditure was x lakhs

So, 50 = 30-x/x * 100

x = 20 lakhs

Income of Company A in the year 2006, 2008 and 2010

= > (30+40+15) = 85 lakhs

Income of company B in the year 2005, 2007 and 2009

= > (20+35+55) = 110 lakhs

Required % = ((110-85)/110)*100 = 22 8/11 % less = 23 %

Required % = (50-45)/45 x 100 = 11.11% ≈ 11%
