Find the difference between total number of LG TV sold by shop D and E together to total number of LG TV sold by shop B and A together?
Correct Answer :
70
Solution :
The correct answer is 70.
Step-by-step Explanation:
Let us first calculate the number of LG TVs sold by each relevant shop using the total number of TVs and the given ratio of MI TV : LG TV.
1. LG TVs sold by Shop A:
Total TVs sold by Shop A = 400
Ratio of MI : LG = 2 : 3
Total ratio parts = 2 + 3 = 5
Number of LG TVs sold by Shop A =
2. LG TVs sold by Shop B:
Total TVs sold by Shop B = 550
Ratio of MI : LG = 6 : 5
Total ratio parts = 6 + 5 = 11
Number of LG TVs sold by Shop B =
3. LG TVs sold by Shop D:
Total TVs sold by Shop D = 600
Ratio of MI : LG = 8 : 7
Total ratio parts = 8 + 7 = 15
Number of LG TVs sold by Shop D =
4. LG TVs sold by Shop E:
Total TVs sold by Shop E = 250
Ratio of MI : LG = 11 : 14
Total ratio parts = 11 + 14 = 25
Number of LG TVs sold by Shop E =
5. Total LG TVs sold by Shop D and E together:
6. Total LG TVs sold by Shop B and A together:
7. Required Difference:
Thus, the difference between the total number of LG TVs sold by shop D and E together and shop B and A together is 70.
