Job Roles

Let the man's rate upstream be x kmph and that downstream be y kmph.

Then, distance covered upstream in 8 hrs 48 min = Distance covered downstream in 4 hrs.

		x x 8	4		= (y x 4)
			5

	44	x =4y
	5

y =	11	x.
	5

Required ratio =		y + x		:		y - x
		2				2

=		16x	x	1		:		6x	x	1
		5		2				5		2

   = 8 : 3.

WBR that is World Book of Records, the London based organization that focuses on maintaining and cataloging the world records has awarded the title of 'Most visited place in the World' to the famous Golden Temple. This holy Shrine has recorded quite an uplift after the successful Heritage street project carried out by the Amritsar department. 

Sri Harmandir Sahib, also known as Golden Temple and the Darbar Sahib, is the holiest Gurdwara and the most important pilgrimage site of Sikhism. It is located in the city of Amritsar, Punjab, India.

From the given data,

=> (2 M + 3W) 8 = (3M + 2W)7

=> 16M + 24W = 21M + 14 W

=> 10W = 5M

=> 2W = M

=> 14W × ? = 7W × 8

? = 4 days

Given 15% of x = 20% of y

=> 15x = 20y

=> x/y = 20/15

=> x : y = 4 : 3

From the given Statements : 

 1. I > W > T > N
 
 2. F = G = C
 

Conclusions are : 

 I. W > I (False)

 II. C > N (True)

Clearly total persons are increased in  28/35 :: 52/65 = 4:5.

As time is inversely proportional to men, so total time will decrease in the ratio 5:4.

Hence, 22.5 x 4/5 = 18 days.
