Question

a railway half ticket cost half the full fare but the reservation charges are same on a half ticket as in a full ticket. one reserved and half reserved tickwt from station a to station b vist rupees 1200 form a linear equation. 20 points..

Answer 1

Let the reservation charge be x rs 
 the cost for full ticket be y rs
so the cost for half ticket is y/2 rs

so now we know
(y+x) + (y/2 + x) = 1200

Answer 2

Let the reservation charge be x rs 
and the first class charge for full ticket be y rs

x+y = 362

y + (2x1/2)y + 2x=554
3y/2 + 2x =554
3y+4x = 1108
 4y+4x = 1448
 y =Rs 340

 x = 362-340 
= 22
