Bullet Train F and Bullet Train G had a total of 196 passengers. When 15 passengers from Bullet Train F moved to Bullet Train G, Bullet Train F had 3 times as many passengers as Bullet Train G. How many passengers were there in Bullet Train F at first?

Bullet Train F |
Bullet Train G |
Total |
| Before |
3 u + 15 |
1 u - 15 |
196 |
| Change |
- 15 |
+ 15 |
|
| After |
3 u |
1 u |
196 |
Total number of passengers
= 1 u + 3 u
= 4 u
4 u = 196
1 u = 196 ÷ 4 = 49
Number of passengers in Bullet Train F at first
= 3 u + 15
= 3 x 49 + 15
= 147 + 15
= 162
Answer(s): 162
