Let the distance be x,

Speed of man in still water = 7.5 km/hr

Speed of stream = 2.5 km/hr

Speed of upstream = 7.5 โ 2.5 = 5 km/hr

Speed of downstream = 7.5 + 2.5 = 10 km/hr

According to the question,

(x/10) + (x/5) = 30

3x/10 = 30

X = 100 km

Loss = C.P โ 7600

Profit = 8350 โ CP

Profit = (1/2)*Loss

8350 โ C.P = (1/2) [C.P โ 7600]

16700 โ 2C.P = C.P โ 7600

3C.P = 16700 + 7600

3C.P = 24300

C.P = Rs. 8100

Selling price = 8100*(120/100) = Rs. 9720

Average speed of the person= 480/6= 80 km/hr

By applying the rule of allegation we get,

= > 1: 3

Ratio between distances covered as 1: 3

So, Distance covered by train= 480*3/4 = 360 km

Efficiency of A and B = 150: 100 = 3: 2

The ratio of time taken by A and B = 2: 3 (2x, 3x)

(1/2x) + (1/3x) = 1/12

5x/(2x*3x) = 1/12

X = 10

The time taken by A and B = 2x, 3x = 20 and 30 days

Total units = 60 (LCM of 20 and 30)

Aโs one day work = 3 units

Bโs one day work = 2 units

Work done in 2 days = 3 + 2 = 5 units

Work done in 24 days = 5*12 = 60 units

Work will be completed in 24 days.

The ratio of share of P, Q and R

= > [75000*3 + 75000*(80/100)*9]: [60000*6 + 60000*(70/100)*6]: [80000*3 + 80000*(120/100)*9]

= > 765000: 612000: 1104000

= > 255: 204: 368

The share of P = Rs. 31875

255โs = 31875

1โs = 125

Total profit = 827โs = Rs. 103375

Directions (6-10):

Import of India in 2013 = 8 million

Export of Nepal in 2010 = 8*(3/2) = 12 million

Import of Nepal in 2010

10โs = 12

1โs = (12/10)

= > 9โs = (12/10)*9 = 10.8 million

Export of India in 2013

8โs = 8

1โs = 1

= > 10โs = (8/8)*10 = Rs. 10 million

Required % = [(10.8 โ 10)/10]*100 = 8 %

Export of Srilanka in 2011 = Rs. 20 million

Import of Srilanka in 2011

10โs = 20

1โs = 2

= > 4โs = 8 million

The import of Srilanka in the year 2012

10โs = 50

1โs = 5

= > 11โs = 55 million

The import of Srilanka in the year 2014

2โs = 50

1โs = 25

= > 1โs = 25 million

The import of Srilanka in the year 2015

5โs = 50

1โs = 10

= > 7โs = 70 million

Required average = (55 + 25 + 70)/3 = 150/3 = 50 million

Import of India in 2014 = Export of Nepal in 2015 = x

Required ratio = [x/(2/5)] : [x/1] = 5: 2

The amount of export for Nepal in 2012

2โs = 28

1โs = 14

= > 5โs = 70 million

The amount of import for Srilanka in 2015

5โs = 25

1โs = 5

= > 7โs = 35 million

Required % = (70/35)*100 = 200 %
