If the exchange rate is Rs 80 for a dollar, what would be the cost of a shirt of Rs 800 in US dollar ?

$10

The correct answer is option (2) : $10

Exchange rate is ₹80 for a dollar,

Cost in US dollars =$\frac{ (\text{Cost in Indian Rupees})}{(\text{Exchange Rate} )}$

Cost in US dollars = (800 INR)/ (80 INR/ USD ) = 10 USD

So, the cost of the shirt is **$10** in US dollars.
