Answer 1

$\huge\boxed{\fcolorbox{red}{yellow}{Shailesh}}$

Let fixed charge be x and charge per extra day =y

x+4y=30

x+6=40

therefore by elimination method we get

-2y=-10

y=5

now by substituting y we get

x+4×5=30

x+20=30

x=10

therefore fixed charge =rs 15

charge per extra day =rs3

hope its correct
