A farm implement manufacturer records the following domestic and export tractor sales (in units) over three quarters:
• Q1: Domestic = 1200, Export = 300
• Q2: Domestic = 1500, Export = 500
• Q3: Domestic = 1800, Export = 600
The ratio of total export sales to total domestic sales across the three quarters combined is:
Options:
(A) 7 : 22
(B) 7 : 25
(C) 14 : 45
(D) 2 : 5
Answer Key:
C
Step-by-Step Solution & Explanation
1. Total export sales $= 300 + 500 + 600 = 1400\text{ units}$.
2. Total domestic sales $= 1200 + 1500 + 1800 = 4500\text{ units}$.
3. Ratio of export to domestic sales:
$\text{Ratio} = \frac{1400}{4500} = \frac{14}{45} = 14 : 45$
