Final answer is approx 6.644 years.
Step-by-step explanation:
Given that a company sold 5.75 million motorcycles and 3.5 million cars in the year 2010. The growth in the sale of motorcycles is 16% every year and that of cars is 25% every year.
So we can use growth formula:
A = P (1 + r)^t
Then we get equation for motorcycles and cars as:
A = 5.75 (1 + 0.16)^t
A = 3.5 (1 + 0.25)^t
Now we need to find about when the sale of cars will be more than the sale of motorcycles. So we get:
3.5 (1 + 0.25)^t > 5.75 (1 + 0.16)^t
3.5 (1.25)^t > 5.75 (1.16)^t
3.5 (1.25)t . 5.75 (1.16)^t
(1.25)^t/(1.16) > 5.75/3.5
(1.25/1.16)^t > 1.64287514286
t·In (1.25/1.16) > In (1.64287514286)
t > In(1.64285714286)/In (1.25/1.16)
t > 6.6436473051
Hence final answer is approx 6.644 years.
