Flow chart question

1. draw a start button.

2. draw a input box n put the charges and Weight.

3. draw a check box and put weight= <10, if yes than (charges C1) = .10*weight.

if no than draw a check box put grams =<40, if yes than (charges C2)= C!+ (.30*weight/5)

4. if not than (charges C3)= C1+C2+(.40*weight/5).

5. Draw  box (processing) and put total charges TC= C1+C2+C3

5. Conncet the boxes of charges with print box n put Charges n Weight.

6. Draw stop button.

while dry run and debugging flow chart is not proper as you told pls eloborate it....and thanks for your support......looking forward......

step 1 : Start

step 2: let charges =0, a=0

step 3: Read weight

step 4: If weight <= 10 gram

        yes. charges = 20 paise. GOTO step 5

        no.   If weight <=50 gram

                   yes. a=roundup {(weight-10)/5}

                            charges = 20+ a*30; GOTO step 5

                    no. a=roundup {(weight - 50)/5}

                             charges = 20+ 8*30 + a*40

step 5: Print "For a weight of"  weight " the charges are "  charges " paise"

step 6: Stop

for the flowchart cited above by Kamal Kishor, there are few mistakes;

1. its asking for input of charges also. it is something that is required to be found out by the flowchart

2. if weight =10 gram, then charges will be Rs. 1.00

    if weight = 8 gram, then charges will be  Rs 0.80

3.  also i think the entire flowchart goes wrong
