The pie chart shows the total number of (sold and unsold) goods by four companies (A, B, C & D). The table shows the items sold out of total good manufactured by these companies.
| Companies | Goods sold out of total goods manufactured |
|---|---|
| A | 90% |
| B | 80% |
| C | 75% |
| D | 4X% |
Out of the total goods sold by A, 53 are defective and rest are non defective, and the ratio of non-defective goods sold by A to non-defective goods unsold by A is 2:1. Find the defective goods sold by A.
Correct Answer :
2
Solution :
To find the correct answer, we will analyze the data from the pie chart and the table step-by-step.
Step 1: Find the total goods manufactured by Company A
From the pie chart:
• Total goods manufactured by all four companies = 200
• Sector percentage for Company A = 35%
Therefore, the total goods manufactured by Company A is:
Step 2: Find the number of sold and unsold goods for Company A
From the table, Company A sold 90% of its manufactured goods:
The remaining goods are unsold:
Step 3: Calculate the non-defective sold goods for Company A
We are given that out of the total goods sold by A (63 goods), 53 are defective.
Therefore, the remaining sold goods are non-defective:
Step 4: Calculate the non-defective unsold goods for Company A
The ratio of non-defective goods sold by A to non-defective goods unsold by A is given as 2:1.
Let the number of non-defective unsold goods be .
So, Company A has 5 non-defective unsold goods.
Step 5: Find the defective unsold goods for Company A
Since the question asks for the defective goods (the question text contains a minor typo asking for "sold" instead of "unsold", since defective sold is already given as 53), we calculate the defective unsold goods:
Thus, the correct option representing the defective unsold goods is 2.
