Detailed Solution

Given that the charges of different tickets are one reserved first class ticket from the stations

A

B

costs Rs 2530. Also, one reserved first class ticket and one reserved first class half ticket from stations

A

B

costs Rs 3810.
Let the cost of full first-class fare be x Then, the cost of half first-class fare is

x 2

. Also, let reservation charges be y per ticket.
The cost of one reserved first-class ticket from the station's A to B

= 2530 ⇒ x + y = 2530 … (i)

The cost of one reserved first-class ticket and one reserved first-class half ticket from stations A to B =3810

⇒ x + y + x 2 + y = 3810 ⇒ 3 x 2 + 2 y = 3810 ⇒ 3 x + 4 y = 7620 … (i i)

Solving above equations, we get x=2500, y=30.
Therefore, the cost of full first-class fare is Rs2500 and reservation charges is Rs30.
Hence, option (4) is correct.
