Solution

Let the cost of fare be Rs.′x′ and the reservation charge be Rs.′y′.

By condition I:x+y=216 ....(i)

By condition II:

one full and one half ticket =1+12=32

cost of half railway ticket is =x2

∴,x+y+x2+y=327

⇒32x+2y=327

⇒3x+4y=654 ....(ii)(after multiplying by 2 )

By solving (i) and (ii) we will get

3x+4y−4x−4y=654−864

∴x=210 and put x=210 in (i) we get y=216−x=216−210=6

∴y=6

Hence, basic fare for one ticket is Rs.210 and reservation fare is Rs.6
