Question

How many millions make three crores?

Answer 1

Hint: For solving this question you should know about the millions and crores. As we know that one million equals 10 lakhs. So, first we will count the 1 crore in lakhs and then this 1 crore in millions. And then we find the 3 crore in lakhs and then we count it in millions. Thus, this question will be solved easily.

Complete step by step solution:
According to the question we have to ask to find how many millions are there in three crores.
So, as we see that there are 10 lakhs in one million. It means if we have to count 1 crore in lakhs then it will be multiplied by 10 with 10 with one million because one million have 10 lakh and 1 crore have 10 times 10 lakh. It means 1 crore has 100 lakhs. And if we see these in the millions then it will be 10 millions there.
For longer calculations if we take some examples then it will be cleared in a better way. So, if we find the millions for 20 crore then we know that 20 crore is a very big number and we can't always write it as a full number everywhere. So, if we calculate it in a short way or if we reduce to his, then as we know that a million is equal to 10 lakhs and as we know that a crore contains 100 lakhs. So, indirectly we can say that:
10 lakh = 1 million
100 lakh = 1 crore
1 crore = 10 (10) lakh
1 crore = 10 million.
So, 20 crore is written as:
20 crore = 2000 lakh
20 crore = 200 (10) lakh
20 crore = 200 millions
If we take our question then 3 crore can be written as 3 crore = 300 lakh
3 crore = 30 (10) lakh
3 crore = 30 millions
So, the 30 millions makes 3 crores.

Note: During solving this type of questions you have to be very much careful for the digits of zero in lakh and crore. If we write them fully explained then always count zeros in every step because if any zero will be more or less in that step that will make the question wrong.
