(i)

100a + 200b = 25/6

600a + 1200b = 25

Multiplying equation by 10, and subtracting from it, we get

1200b = 15

b = 15/200 = 1/80

Putting equation, we get

60a + 3 = 4

60a = 1

a = 1/60

Now, a= 1/u = 1/60 and b = 1/v = 1/80

u = 60 and v = 80

Therefore, speed of train = 60 km/h and speed of bus = 80 km/h

Hope you understand.....................................
