CocaColas worldwide sales as of December 31 2011 was 267 bil
Solution
This question requires the application of compounding formula, which is:
FV = PV * (1 + r)n
Question 1
In 2011, sales in Italy were = 26.7 bil * 9% = 2.403 bil
Growth rate for future 42 years is 10.26%
Hence, sales in 2053, FV = 2.403 * (1 + 10.26%)42 (Using same formula mentioned above)
FV = 2.403 * 60.4722 = 145.3146
Question 2
For growth rates during different periods,
1934 - 1936: 1,000,000 = 243,000 * (1 + r)2 => 4.1152 = (1 + r)2 => 2.0286 = (1 + r) => r = 102.86%
1936 - 1939: 4,500,000 = 1,000,000 * (1 + r)3 => 4.5 = (1 + r)3 => 1.6510 = (1 + r) => r = 65.10%
1934 - 1939: 4,500,000 = 243,000 * (1 + r)5 => 18.5185 = (1 + r)5 => 1.7928 = (1 + r) => r = 79.28%
Question 3
PV = 4,500,000, r = 79.28%, n = 6
FV = 4,500,000 * (1 + 79.28%)6
FV = 4,500,000 * 33.204050
FV = 149,418,225.7 --> Answer
