1. The number of rooms at Hotel G is 10 less than twice the number of rooms at Hotel 11. If the total number of rooms at Hotel G and Hotel H is 425 , what is the number of rooms at Hotel G?
- A. 140
- B. 140
- C. 140
- D. 140
Answer: Option D
Explanation:
1st condition, G = 2H - 10
2nd condition, G + H = 425
H = 425 - G
Now, G = 2(425 - G) - 10
G = 850 - 2G - 10
G + 2G = 840
3G = 840
G = 280
2nd condition, G + H = 425
H = 425 - G
Now, G = 2(425 - G) - 10
G = 850 - 2G - 10
G + 2G = 840
3G = 840
G = 280
