- distance by taai say X
by train = 450-x
taai+train=8130
15*X+(450-X)*21=8130
i.e X=220
train=450-220=230km - 11 years agoHelpfull: Yes(3) No(0)
- 15x+21y=8130 ----(1)
x+ y=450------------(2)
solving eq (1) & (2),
we get ,x=220 & y=230

- let distance travelled by taai=x
cost of 1km by taai=Rs. 15
total cost of distance travelled by taai=15x
Distance travelled by train=450-x
cost of 1 km by train=Rs. 21
total cost by train=21(450-x)
now
15x+21(450-x)=8130

x=220
journey travelled by train=450-220=230km - 10 years agoHelpfull: Yes(0) No(0)
- 230 km traveled by train (230*21=4830)
220 km traveled by taxi (220*15=3300)
4830+3300=8130.
which is the total amount paid.
so journey traveled by train is 230 km. - 9 years agoHelpfull: Yes(0) No(0)
