1. Quantitative expression of economic problems: Statistics is an essential tool for an economist

to understand the problems of an economy through quantitative data. Example: The problem of poverty in India can be quantitatively expressed as there is a substantial decline in poverty ratios

in India from 55% in 1973to 36% in 1993. 2. Inter-sectoral and inter-temporal comparisons: This

quantitative data is further used to make inter sectoral comparison ,i.e. across different sectors of the economy and inter-temporal comparisons „i.e. over different plan periods of the rural and urban unemployment.

3. Cause and effect relationship: Different sets of data are used to find the cause and effect relationship. This enables policy makers to formulate policy to solve the problem of an economy

It is the time period between the time of purchase of inventory and collections of any receivables on account of sale of the inventory or we can say it is time between acquisition of assets for processing and its final realisation in cash and cash equivalents. 

Adults talked of love and preached about it but they did not act lovingly. This is the moment of realization, the speaker begins to understand that adults are hypocritical and do not practice what they preach to children. They do not refrain from harming others. The poet certainly does not approve of their approach.

In the poem childhood by Markus Natten, the words hell and heaven depicts the transformation from being a innocent child in to an individual hypocritic adult.

The childhood is the heaven where the child has spirit of vengeance or urge for power, where the adult life is the hell with man running all around conquering the world.

Every human being in this world at some point fall into the life of hell from innocent heaven.

He expresses concern over his childhood’s disappearance. Childhood cannot be regained. It keeps our life aloof from the world of hypocrisy, bitter reality and materialism.

According to the poem, the process of growing up involves the attainment of mental maturity. A person is said to be grown up when he has become logical, rational and is able to build his own thoughts. A grown up has the power to distinguish between reality and fantasy.
A grown up individual understands the actions of others just as the poet recognises the hiatus between the preaching and the practice of the adults. He realises the hypocrisy and the double standards maintained by the adults. A mature individual also asserts his thoughts and opinions. The poet realises that he himself is the master of his mind and can form thoughts and opinions of his own.

The poet, basically, seems to be obsessed about his childhood and, more so, about its loss. He feels very nostalgic and lament over the fact that his childhood will never come back.  

• The poem "Childhood" presents a real picture of what man is.
• The poet builds a contrasting image of childhood and the adults' views and perspective.
• During childhood, a child is very innocent and is filled with love and purity. As he starts growing into an adult, the negative emotions like hatred and jealously steps into the person.
• Although the adults preach of living in harmony and with love but in reality they do not practice such things.

The poet can find his lost childhood in the picture of an infant. Yes he has lost his childhood irrevocably. The poem Childhood by Markus Natten is about his lost childhood. He also wants to know where his innocence has gone. He feels he has left it somewhere in the past. May be it has gone to the infant that he used to be. But he is sure he no longer possesses the joys, carelessness and innocence of his childhood.

The first and most important reason the poet seems confused is because, he does not understand when he stopped being a child and when he became an adult. Whilst trying to find his childhood, he reveals more things about himself that show his confusion. He is confused by the fact that Heaven and Hell are not real places unlike what he learnt growing up. He is confused as to why adults are so hypocritical. He sees adults around him preaching love, but they never practise it themselves, which leave him confused. He suddenly realises that he is now an adult who can think for himself and the sudden burden of responsibility confuses him as it is not something he experienced as a child, as he was always told what to do as a child.

Poet feels that grown up people do not act on what they preach.

The child in the poem Childhood does not think highly of the adults. They say that the adults tell us to preach love but fail to do so themselves.

Hence, the child calls the adult hypocrites who say something but do something else.

The child interprets that the adults talk about love but they do not preach so themselves and ends up calling them hypocrites.
