Answer:

Q3. ten 50 notes

fifteen 100 notes

Q4. fixed charge = 25

additional charge = 3

Step-by-step explanation:

3)

let no. of 50 notes = x

and no of 100 notes = y

x + y = 25 ( total no of notes ) eq 1

50x + 100y = 2000 ( total money ) eq 2

on multiplying eq1 with 50 on both sides you get

50x + 50y = 1250 eq3

eq2 - eq3

you get y = 15

and on substituting y you get X = 10

4)

let fixed charge be x

and additional charge be y

Rs 27 - 7 days => 4 extra days

Rs 21 - 5 days => 2 extra days

x + 4y = 27 .. eq1

x + 2y = 21 .. eq2

eq1 - eq2

you get y = 3

and on substituting y you get x = 15
