Directions (1-5):

Quantity I:

Present age of Asha = 12 + Present age of Rahul

After 10 years, the ratio of ages of Rahul and Asha = 3: 5 (3x, 5x)

5x – 3x = 12

2x = 12

x = 6

The age of Rahul, after 2 years = 3x – 5 + 2 = 15 years

Quantity II:

The ratio of present age of Naveen and Priya = 2 : 1

The ratio of present age of Gowrish and Priya = 7 : 4

The present age of Naveen, Priya and Gowrish = 8 : 4 : 7

The age of Naveen, after 6 years = 30 years

The present age of Naveen = 24 years

8’s = 24

1’s = 3

The age of Gowrish before 6 years = 7x – 6 = 15 years

Quantity I = Quantity II

Profit share=19000 * 12 : 28000 * 6 =19:14

Quantity I,

A’s share

= > 19/33*16500

= > Rs.9500

Quantity II,

B’s share

= > 14/33 * 16500

= > 7000

Quantity I > Quantity II

Quantity I,

300 = (80-60) * (5/18) * x

300 = 20 * (5/18) * x

x = 54 seconds

Quantity II,

x = 60 * 5/18 * 18

x = 300m

300+700 = 80 * 5/18 * x

x = 45 seconds

Quantity I > Quantity II

Quantity I:

P and Q completes 3/4th work in 5 days, so complete 1 work in 4/3 * 5 = 20/3 days

Q complete 3/5 work in 6 days, so complete work in 5/3 * 6 = 10 days

So in 1 day P completes = 3/20 – 1/10 = 1/20

So to complete 1/5th work = 1/5 * 20 = 4 days

Quantity II:

Length of train = 2.5 * 60 = 150 km

So time taken to cross platform of length 60 km with speed 60 km/hr

= (150+60)/60

= 3.5 hrs

Hence, Quantity I > Quantity II

Quantity I:

Total number of balls = 4 + 3 + 5 + 6 = 18 balls

n(S) = 18C2

Probability that both the balls are either Orange or blue

n(E) = 5C2 or 6C2

P(E) = n(E) / n(S) = [5C2 or 6C2] / 18C2

P(E) = 25 / 153

Quantity II:

n(S) = 18C4

Probability that all the balls are of different colours

n(E) = 4C1 and 3C1 and 5C1 and 6C1

P(E) = n(E) / n(S) = [4C1 or 3C1 or 5C1 or 6C1] / 18C4

P(E) = (4 * 3 * 5 * 6) / [(18 * 17 * 16 * 15) / (1 * 2 * 3 * 4)]

P(E) =  2 / 17

Quantity I > Quantity II

Directions (6-10):

The total number of male television viewers of Star news

= > 75000*(12/100)*(8/15) = 4800

The total number of female television viewers of Star Vijay

= > 75000*(21/100)*(8/15) = 8400

Required difference = 8400 – 4800 = 3600

The total number of television viewers of Polimer TV

= > 75000*(15/100) = 11250

The total number of female television viewers of Colors TV

= > 75000*(20/100)*(2/3) = 10000

Required ratio = 11250 : 10000 = 9 : 8

Total number of television viewers of Times Now

= > 75000*(14/100) = 10500

Total number of male television viewers of ZEE TV

= > 75000*(18/100)*(4/9) = 6000

Required % = (10500/6000)*100 = 175 %

The total number of male television viewers of Polimer TV, Star Vijay and Colors TV together

= > 75000*(15/100)*(5/9) + 75000*(21/100)*(7/15) + 75000*(20/100)*(1/3)

= > 6250 + 7350 + 5000 = 18600

Required average = 18600/3 = 6200

Total number of female television viewers of Star news

= > 75000*(12/100)*(7/15) = 4200

Total number of male television viewers of ZEE TV

= > 75000*(18/100)*(4/9) = 6000

Required % = [(6000 – 4200)/6000]*100 = 30 % less
