How much is a Billion? - Numerical Reasoning Test & Aptitude Training in SLA Chennai

sla jobs chennai complaints




Time and time again a little niggle arises in some of the psychometric numerical reasoning questions that causes a little doubt for some people.

What is a billion? How many zeroes are there in a billion? The short answer to the question in the title is, ‘it all depends on where you live.’

Geographical relativism is alive and kicking. The trouble here is that some countries have adopted what is sometimes called a ‘short scale’ billion which is a thousand times a million or 10^9 in size.

At the same time, other countries have adopted a ‘long scale’ billion which is a million times a million or 10^12 in size. Most English-speaking countries tend to use the short scale billion and most of Europe tends to use the long scale billion.

Britain used to be in line with Europe but officially changed to the short scale billion in the 1970s. Apparently, the French developed both the systems. In India, one billion is represented by 10 ^ 9.

It is good to know and sometimes must to know the different representations of Billion while solving a numerical reasoning test. Most companies test you on both aptitude as well as technical skills.
