Question

A lending library has a fixed charge for the first two days and an additional charge for each day thereafter. Sunil paid Rs 28 for a book kept for seven days, while Sohail paid Rs 32 for the book he kept for nine days. Find the charge for each extra day.​ *

Answer 1

Answer:

you can solve like this

Let the fixed charge be Rs. x

and the extra charge be Rs. y

x+4y=27⟶(i)

x+2y=21⟶(ii)

On substracting (i) and (ii),

2y=6

y=3

putting y in (i),

x+4(3)=27

x=15

∴x=Rs.15 and y=Rs. 3

∴ Fixed charge =Rs. 15

∴ Charge for each extra day =Rs. 3 .
