Correct Answer :
280
Solution :
Correct Answer: The correct answer is 280.
Step-by-step explanation:
Step 1: Calculate the total number of MI TVs and LG TVs sold by Shop B.
From the given table, for Shop B:
Total number of TVs (MI + LG) = 550
Ratio of MI TVs : LG TVs = 6 : 5
Total ratio parts = 6 + 5 = 11
Number of MI TVs sold by Shop B:
Number of LG TVs sold by Shop B:
Step 2: Calculate the number of non-defective TVs for each brand.
For brand MI:
Defective percentage = 40%
Non-defective percentage = 100% - 40% = 60%
Number of non-defective MI TVs:
For brand LG:
Defective percentage = 60%
Non-defective percentage = 100% - 60% = 40%
Number of non-defective LG TVs:
Step 3: Calculate total non-defective TVs sold by Shop B.
Total non-defective TVs (MI + LG):
Therefore, the total number of non-defective TVs sold by Shop B is 280.
