Answer: One Arab is equal to 1 billion in the Indian numbering system. So, to convert 1 Arab Dollar to Indian Rupees, you would need to multiply it by 1 billion.

1 Arab Dollar = 1,000,000,000 (1 billion) Dollars

To convert this to Indian Rupees, you can use the current exchange rate. Let’s assume the exchange rate is 75 Rupees per 1 US Dollar:

1 Arab Dollar = 1,000,000,000 Dollars 1 US Dollar = 75 Rupees

Now, multiply the number of Arab Dollars by the exchange rate:

1,000,000,000 Dollars x 75 Rupees/Dollar = 75,000,000,000 Rupees

So, 1 Arab Dollar is equal to 75,000,000,000 Indian Rupees.

In summary, 1 Arab Dollar is equivalent to 75 billion Indian Rupees when using an exchange rate of 75 Rupees per 1 US Dollar.
