Question

What is the value of one crore in million?

Answer 1

Hint: In this question, we have to know about the Indian and the international system of units. Thereafter, we can express the given quantity, which is one crore in its decimal representation. Then, we can divide it by one million to express the quantity in terms of million.
Complete step-by-step answer:

In this question, we have to change the units of quantity in different units, i.e. from crores to million.
Also, we know that to express a quantity Q in terms of a unit w, we can write
$Q=\dfrac{Q}{w}\times w................(1.1)$
Thus, the value of Q in the units of w should be $\dfrac{Q}{w}$.
In this question, let the actual value of the quantity be q. Now, we know that the value of one crore is given by
1crore = 10,000,000.
Thus, we can take Q=10,000,000 in equation (1.1). Then, by taking w= 1million = 1,000,000 in equation (1.1), we obtain
$1\text{ crore= Q= }\dfrac{Q}{w}\times w=\dfrac{10,000,000}{1,000,000}\times 1\text{million=10million}............\text{(1}\text{.2)}$
Thus, we find that the value of 1 crore in million is given by
1crore = 10 million
Which is the required answer to the question.
Note: We should be careful that in equation (1.2), the value of Q should be written in terms of just a number and not in terms of any units as we are putting the units in terms of w by multiplication.
