Answer:

case 1 the change received back is 5 rs

case 2 the change received is 10 rs

Step-by-step explanation:

Now assume that you are at a grocery shop and you are buying all those items which are provided in given table, here you have 500 rupees in your hand  

case 1

here       items = which are given in table

              rate = the rate of the items at gm or kg

              amount = total cost of the item

         item                            rate                     amount  

  300 g coffee          per 100 g 90             3×90 =270

  200 g biscuits        per 100 g 45             2× 45 = 90

  750 g pulses          per 100 g 10             7.5 ×10 =75  

  1 kg potato              per  1 kg 60                 1× 60 =60  

  total                                                                        495

 change received back  500- 495 = 5 rupees  

case 2    

           item                            rate                amount

   500 g sweets            per 100 g 50       5 × 50 = 250

2 loaves bread             per 1 piece 30     2 × 30 = 60

6 ice creams                  per 1 piece 15       6× 15 = 90

300 g  butter                 per 100 g 30        3× 30 = 90

total                                                                          490  

change received back  500 - 490 = 10 rupees                                  

note : the cost of items  may be change in different stores and all the amounts which i provided above are for our convenience
