Let the full fare of first class ticket costs Rs x and reservation charges be Rs y.
Given that one full reserved first class ticket costs Rs. 216 and one full and one half reserved first class ticket costs Rs 327.
x + y = 216 . . . (i)
or y = 216 - x
(x + y) + [(x/2) + y] = 327 . . . (ii)
216 + [(x/2) + y] = 327
(x/2) + y = 327 - 216
(x/2) + y = 111 . . . (iii)
substituting y = (216 - x) in (iii) .....
(x/2) + (216 - x) = 111
216 - (x/2) = 111
(x/2) = 105
x = 110
y = 216 - 110 = 106
Basic first class full fare = Rs. 110
Reservation charge = Rs. 106
