Direction (1-5) :

Quantity I:

Selling price of the article = 400*(90/100) = Rs. 360

Cost price of the article

= > CP*(120/100) = 360

= > CP = 360*(100/120)

= > CP = Rs. 300

Quantity II:

Selling price of the book = 350*(92/100) = Rs. 322

Cost price of the book = 322*(100/115) = Rs. 280

Quantity I > Quantity II

Quantity I:

According to the question,

(4800*5)/(6400*x) = (3/8)

24000/6400x = 3/8

24000*8 = 6400x*3

X = (32400*8)/(6400*3)

X = 10 months

Quantity II:

According to the question,

(5*8)/(8x) = (1/2)

X = 10 months

Quantity I = Quantity II

Quantity I:

x/(10-6) – x/(10+6) = 6

x/4 – x/16 = 6

3x/16 = 6

X= 32 km

Quantity II:

Speed of still water (x) = 20 km/hr,

Speed of stream (y) = 8 km/hr

D = t*[(x2 โ y2)/2x]

= > 4*[(202 – 82)/(2*20)]

= > 4*(400 – 64)/40

= > 4*(336/40)

= > 33.6 km

Quantity I < Quantity II

Quantity I:

SI = (P*n*r)/100

7500 = (P*5*8)/100

P = (7500*100)/40 = Rs. 18750

Quantity II:

C.I = P*[(1 + (r/100))2 โ 1]

8800 = P*[(1 + 15/100)2 โ 1]

8800 = P*[(115/100)2 โ 1]

8800 = P*[(23/20)2 โ 1]

8800 = P*[(576/400) โ 1]

8800 = P*[176/400]

P = (8800*400)/176 = Rs. 20000

Quantity I < Quantity II

Quantity I:

Total probability n(S) = 16C3

Required probability n(E) = 1 โ P(none is Pink)

Probability of getting none is Pink balls,

P(E) = n(E)/n(S) = 11C3/16C3

= > 33/112

Required probability = 1 โ (33/112) = 79/112

Quantity II:

Total probability n(S) = 16C2

Required probability n(E) = 7C2 or 4C2

P(E) = n(E)/n(S) = 7C2 or 4C2 / 16C2

= > (21 + 6)/120 = 27/120

= > 9/40

Quantity I > Quantity II

Direction (6-10) :

The total number of male Tamil newspaper readers in the year 2012 and 2014 together

= > 18000*(2/3) + 28000*(4/7)

= > 12000 + 16000 = 28000

The total number of female English newspaper readers in the year 2013 and 2015 together

= > 22000*(5/11) + 23000*(12/23)

= > 10000 + 12000 = 22000

Required ratio = 28000 : 22000 = 14 : 11

The total number of Tamil newspaper readers in all the given years together

= > 18 + 24 + 28 + 27 + 30 + 33 = 160 thousands = 160000

The total number of English newspaper readers in all the given years together

= > 14 + 22 + 29 + 23 + 28 + 34 = 150 thousands = 150000

Required difference = 160000 โ 150000 = 10000

The total number of female Tamil newspaper readers in the year 2013, 2015 and 2017 together

= > 24000*(5/8) + 27000*(14/27) + 33000*(6/11)

= > 15000 + 14000 + 18000 = 47000

The total number of male English newspaper readers in the year 2014

= > 29000*(15/29) = 15000

The total number of female English newspaper readers in the year 2017

= > 34000*(8/17) = 16000

Required % = (15000/16000)*100 = 93.75 %

The total number of Tamil newspaper readers in the year 2013 and 2015 together

= > 24000 + 27000 = 51000

The total number of English newspaper readers in the year 2012 and 2016 together

= > 14000 + 28000 = 42000

Required % = [(51000 โ 42000)/42000]*100 = 21.42 % = 21 % more
