A. 0.83:1
B. 0.89:1
C. 0.94:1
D. 1.06:1
Answer: B
Explanation:
Step 1: Make sure you get the ratio the correct way round. Start by writing this down in a ratio format: Grade A value : Grade C value.
Step 2: Calculate value of 2 classes of widget:
Grade A: 20,000/50 x 500 = 200,000
Grade C: 75,000/50x150 = 225,000
Step 3: Write these values underneath the ratio you wrote down in Step 1:
Grade A : Grade C = 200,000 : 225,000 = 0.8888 : 1
