Answer 1

Hint: Here this question belongs to the unit conversion topic. This means that we have to convert the amount of money from one currency to another. Here we are also given the conversion rate to convert one currency to another. So, to convert the amount of money from one currency to another, we multiply the conversion rate of the two currencies by a suitable number.

Complete step-by-step answer:
The dollars and Indian rupees are the currencies for money.
The given question requires us to convert the amount of money from dollars to Indian rupees.
We are also given that one dollar consists of $75$ Indian rupees.
Then, let the amount of money in Indian rupees that correspond to $5$ million dollars be x.
So, to convert $5$ million dollars into Indian rupees, we follow the unitary method where we multiply the unitary base conversion of dollars to Indian rupees by a suitable number to get to the final answer.
So, $1$ dollar $=$ $75$ Indian rupees
Now, multiplying both the sides of the equation with $5$ million, we get,
 $\Rightarrow 1\times 5,000,000$ dollars $=75\times 5,000,000$ Indian rupees
Carrying out the calculations, we get,
 $\Rightarrow 5,000,000$ dollars $=375,000,000$ Indian rupees
So, the value of $5$ million dollars in Indian rupees given that one dollar is equal to $75$ Indian rupees is $375$ million Indian rupees.
So, the correct answer is “ $375$ million Indian rupees”.

Note: Every country has its own currency of money. Dollar is the currency of the United States and Indian rupee is the currency of India. Dollar is also the global currency as the majority of the international trades are settled in dollars. Hence, it is important for us to know the conversion rates of different currencies into each other. We must take care of the calculations while dealing with such questions.
