Question

How many Lakhs make a billion?

Answer 1

Hint:
 Compare the Indian number system with the international number system to detect the difference in counting and the basic difference or similarity between them. Write the positions of one billion and similarly one lakh to determine the answer.

Complete step by step answer:
The number system is the system of representing numbers. There are two types of number systems namely the Indian number system and the International number system. The main difference between the Indian number system and the International number system is the placement of the separators. In the International number system, millions are written after thousands. In the Indian system, lakhs are written after thousands. Millions and billions are used in the international number system whereas lakhs and crores are used in the Indian number system. Up to ten thousand both Indian and international number systems are the same.
Now, in the Indian system, one lakh appears after ten thousand while in the international system a hundred thousand appears. Next is 10 lakhs in the Indian system and one million in the international system. Ongoing further in Indian system we have one crore which we can call 100 lakhs and in the international number system, it is 10 million. Increasing a step further in the Indian system we have 1,000 lakhs and in the international system, it is 100 million. Now, the next place in the Indian system will be 10,000 lakhs and in the international system, it will be 1 billion.
Hence, we can conclude that 10,000 lakhs make a billion.

Note:
One may note that we can also get the answer by dividing 1 billion with 1 lakh. In the above solution, we have replaced 1 crore with 100 lakhs. This conversion was necessary to get the answer. Do not get confused by the commas or separators used in both the Indian number system and the international number system. Indian number system uses a comma after every two place values after the hundredth digit, while the international number system uses a comma after every three place values.
