Question

The parking charges of a car at New Delhi Railway station for first two hours are Rs 50 and Rs 10 for subsequent hours, Write down an equation and draw the graoh of this data. Read the charges from the graph:
(i) For one hour

Answer 1

Lat $t$ be time & $C$ be cost

$C=50\times 2+10(t-2)$ if $t>2$

$\Rightarrow C=100+10(t-2)$

$\Rightarrow C=80+10t$

for $t>2$,

$C=50\times t$

$\therefore$ Cost for $1$ hour $=Rs.50/-$
