The Ministry of Women and Child Development has launched #Childline1098 childline contest to spread awareness on human trafficking. 

Human trafficking is the trade of humans for the purpose of forced labour, sexual slavery, or commercial sexual exploitation for the trafficker or others.

The WCD Ministry has invited people to share images of the logo of Childline 1098, the nationwide emergency helpline for children in distress, that they spot at unique locations and send it with a tagline to win a cash price, in a bid to spread awareness on trafficking.

The contest has been organised to mark 'World Day against Trafficking in Persons' on July 30.

The Childline has been operating at 450 locations, including 76 key railway stations, across the country.

Nonpartisanism is a lack of affiliation with or bias toward a political party.

There is no difference except for the fact that the first one gives a hint that the function fun() is probably in another source file.

A lower CPA may be accompanied by lower sales volume, reducing overall profit.

Let the missing numbers be x, y, a and b

x + y = 8 ---- (1)
a - b = 6 ---- (2)
x + a = 13 --- (3)
y + b = 8 ---- (4)

2x + a + y = 21 --- From (1 & 3)
a + y = 14 ----  From (2 & 4)

Substitute (2 & 4) in (1 & 3)

2x + 14 = 21
2x = 7
x = 3.5

From (1) ---> 3.5 + y = 8
=> y = 8 - 3.5 = 4.5

a + y = 14 => a = 14 - y = 14 - 4.5 => a = 9.5
From (4) ---- y + b = 8 => b = 8 - y = 8 - 4.5 = 3.5

Hence,
x = 3.5
y = 4.5
a = 9.5
b = 3.5
