Question 1.

Problem 2.7 from textbook Peso Changes. In December 1994, the government of Mexico officially changed the value of the Mexican peso from 3.2 pesos per dollar to 5.5 pesos per dollar. What was the percentage change in its value? Was this a depreciation, devaluation, appreciation, or revaluation? Explain.

Question 2.

Problem 2.10 from textbook 10 Ranbaxy (India) in Brazil. Ranbaxy, an India-based pharmaceutical firm, has continuing problems with its cholesterol reduction products price in one of its rapidly growing markets, Brazil. All product is produced in India, with costs and pricing initially stated in Indian rupees (Rps) but converted to Brazilian reais (R$) for distribution and sale in Brazil. In 2009, the unit volume was priced at Rps21,900, with a Brazilian reais price set at R$895. But in 2010, the reais appreciated in value versus the rupee, averaging RPS 26.15= 1real. In order to preserve the reais price and product profit margin in rupees, what should the new rupee price be set at?
