x+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

Answer 2

Answer:

Let the reservation charges be Rs.r and cost of full ticket of first class be Rs. y. It is given that one reserved first class ticket from the station A to B costs Rs. 2530. Also, one reserved first class ticket and one reserved first class half ticket from A to B costs Rs. 3810, therefore, a+y= 2530. .(1) and since railway half ticket costs half the full fare, but the reservation charges are the same on a half ticket as on a full ticket so we get (z + y) - (r+ ) = 3810 = dr +3y = 7620......(2) Multiplying equation 1 by 3 we get. 3r - 3y = 7590. . (3) Now subtracting equation 3 from equation 2, we get a = 30. Now substitute the value ofa in equation 1 that is: 30 +y = 2530 implies y = 2500 Hence, the full first class fare from station A to B is Rs. 2500.
