Question

Refer situation 2 3. What will a person have to pay for travelling a distance of 30km? a) Rs.185 b) Rs.289 c) Rs.275 d) Rs.305​

Answer 1

Answer:

b) Rs 289

step by step explanation :

let fixed charge be Rs x and running charges be Rs y

for the journey of 8km is paid Rs 91

x+8y=91

for the journey of 14km the charge paid is Rs145

x+14y=145

using substitution method

we get,

x= 19

y=9

ATQ,

if a person travels 30km

total charged = fixed charges + running charges * 30

= 19 + 30*9

= 19 + 210

= Rs 289

Answer 2

The correct option is; b) Rs 289.

A person has to pay 289 for traveling a distance of 30km.

let see;

a charge will be Rs x and running charges be Rs y  for the journey of 8km is paid Rs 91

x+8y=91

By using the substitution method;

we have,

x= 19

y=9

if a person travels 30km.

then,

total charged = fixed charges + running charges × 30

= 19 + 30×9

= 19 + 210

= Rs 289

Hence, A person has to pay 289 for traveling a distance of 30km.

The correct option is; b) Rs 289.
