In a particular family, each boy has as many brothers as the sisters, but each girl has twice as many brothers as that of sisters.

How many numbers of siblings are there in the family?

Answer : 

There are 4 boys and 3 girls in the family.

Let the number of boys be 'x' and the number of girls be 'y'.
The first statement says that each boy has equal numbers of 

brothers and sisters
(x - 1) = y

The second statement says that every girl has twice as many brothers as that of sisters
2 (y - 1) = x

solving above two equations will result in  
p = 4.
q = 3

In a race of 600m X can beat Y by 60m and in a race of 500m Y can beat Z by 50m. By how many metres will X beat Z in a race of 400m?

a) 76 m

b) 74 m

c) 72 m

d) 78 m

Answer : 76 m 

When X runs 600m, Y would run (600-60) = 540m 
and When X runs 400 m, Y runs (540/600)×400 = 360m

When Y runs 500 m, Z runs (500-50)= 450m
and When Y runs 360 m, Z runs (450/500)×360 = 324m

i.e., When X runs 400 metre, Y runs 360 metre and Z runs 324 metre.
Hence, X beats Z by (400-324)=76 metre in a race of 400 m

(optional question)

In biology, the term mutualism refers to a mutually beneficial relationship between two species. The later economic theory of mutualism is based on the labour theory of value, which states that the true cost of an item is the amount of labour that was required to produce it. Hence, goods should not be sold for more than the cost of acquiring them. Mutualism is closely associated with anarchism, because its principles were set forth in the mid- nineteenth century by the French politician and philosopher Pierre-Joseph Proudhon – the first person to define himself as an “anarchist”. 

The main tenets of mutualism are free association  and free credit. In a mutualist workplace, workers with different skills form an association to create a product or service. Though dependent on each other, the workers are not subordinated as in a capitalist enterprise. Mutual banks, also called credit unions, operate on the belief that free credit enables profit to be generated for the benefit of the union’s members rather than bankers. 

Modern-day mutualism is sometimes described as free-market socialism. Proponents of mutualism support a free market economy, but object to capitalism because of the inequalities created by government intervention. Many mutual businesses and banking establishments exist today, espousing Proudhon’s Co-operative model. 

[Use Ture, False, Cannot say for the below questions]

a) Proudhon’s economic theory of mutualism was influenced by biological mutualism. 

b) Mutual banking establishments do not operate on a for-profit basis.

c) The labour theory of value is defined as: only the person who made an item should profit from its sale.

Mechanization is defined as the process of using machines to perform work that had previously been performed by people. Automation, which is an extension of mechanization, is defined as the process of performing mechanical operations with minimal or no human involvement. Automation is commonly used whenever an organization faces difficulties producing a product of a consistent quality, as well as when work is monotonous or unsafe for employees. 

Automation systems can be either hard or soft. Soft automation systems are adaptable, thus allowing them to perform several different functions. Hard automation systems have each machine perform one specific function. As a result, these systems are less adaptable than soft automation systems. From the information given above, it can be validly concluded that:

a) There are at least some automated systems that require considerable human involvement to perform mechanical operations

b) If an organization can consistently produce a high quality product, it is unlikely that it will use an automated system.

c) No hard automation system is more adaptable than a soft automation system.

d) Any organization that uses an automated system has found its work to be monotonous or unsafe for employees.
