Question

Between April 2011 and April 2016, the price of a U.S. postage stamp increased from $0.41 to $0.46. The price of a U.S. postage stamp has increased approximately ________ in terms of Indian rupees and ________ in terms of Chinese yuan.

Answer 1

The price of a U.S. postage stamp has increased approximately 63% in terms of Indian rupees and 10% in terms of Chinese yuan.

Step-by-step explanation:

the exchange rate between the US dollar and the Indian rupee:

April 2011 = 45.54 Indian rupees per dollar x $0.41 = 18.67 Indian rupees

April 2016 = 66.16 Indian rupees per dollar x $0.46 = 30.43 Indian rupees

change in Indian rupees = (30.43 - 18.67) / 18.67 = 63%

the exchange rate between the US dollar and the Chinese yuan:

April 2011 = 6.61 Chinese yuan per dollar x $0.41 = 2.71 Chinese yuan

April 2016 = 6.48 Chinese yuan per dollar x $0.46 = 2.98 Chinese yuan

change in Chinese yuan = (2.98 - 2.71) / 2.71 = 10%
