Question: 2
John had 100 dollars. The exchange rate converts the amount in US dollars to a number in Pak
Rupees by directly multiplying by the value of the exchange rate. By what amount did John’s $100
increase in terms of Pak Rupees from Jan. 9 to Feb. 8?
Show/Hide Explanation
Correct Answer: E
One dollar converted to 39.1 Rupees on Jan. 9. Hence, 100 dollars converts to 39.15 × 100 = 3915 Pak
Rupees. On February 8, it converted to 39.65 Rupees. Hence, on that day, 100 dollars converted to 39.65 ×
100 = 3965 Rupees. The increase in terms of Indian Rupees is 3965 – 3915 = 50. The answer is (E).
