Let us take the speed of the boat in still water be x km/hr,

120/(x+8) = (1/3)*(120/(x-8))

3x – 24 = x + 8

2x = 32

X = 16

Speed of the boat in still water = 16 km/hr

Let the cost price be x,

Selling price = (120/100)*x = 6x/5

Marked price*(75/100) = 6x/5

MP = 8x/5

The profit earned was Rs.100 less than the discount,

According to the question,

= > (8x/5 – 6x/5) – (6x/5 – x) = 100

= > 2x/5 – x/5 = 100

= > x/5 = 100

Cost price = Rs. 500

Selling price = 500*(120/100) = Rs. 600

Total Balls = 18

Required Probability = 4C3 / 18C3 = 1/204

5 years ago, Agila: Hema = 3: 2 (3x, 2x)

Present ages of Agila and Hema = 3x + 5, 2x + 5

Three years ago, Agila’s age is equal to Hema’s age after 2 years,

= > 3x + 2 = 2x + 7

= > x = 5

Present age of Agila = 3x + 5 = 20 years

(x – 6)/24 + x/30 = 1

(30x – 180 + 24x)/720 = 1

54x – 180 = 720

54x = 900

X = 900/54 = 50/3 days

Direction (6-10) : The total number of boys in School P

= > 60000*(15/100)*(52/100) = 4680

The total number of girls in School R

= > 60000*(12/100)*(46/100) = 3312

Required difference = 4680 – 3312 = 1368

The total number of girls in School P, Q and S together

= > 60000*(15/100)*(48/100) + 60000*(18/100)*(52/100) + 60000*(16/100)*(54/100)

= > 4320 + 5616 + 5184 = 15120

Required average = 15120/3 = 5040

The total number of students in School R

= > 60000*(12/100) = 7200

The total number of boys in School T

= > 60000*(20/100)*(56/100) = 6720

Required ratio = 7200: 6720 = 15: 14

The total number of girls in School U

= > 60000*(19/100)*(50/100) = 5700

The total number of boys in School Q

= > 60000*(18/100)*(48/100) = 5184

Required % = (5700/5184)*100 = 110 %

The central angle for School T

= > (20/100)*360 = 720
