Question

Cost of five pizzas is 725 and six pastries is 210 if i want to purchase three pizzas and 12 pastries how much should i pay ? Number of even number to.Odd number from the set of naturalnumber from 30 to 50

Answer 1

given cost of 5 pizzas = Rs.725

       if 5 pizzzas cost --------> 725

           1 pizza cost-------------> X       now cross multiply to find X ,

            ⇒ 5X=725  

            ⇒X= 145            ie, cost of 1 pizza is Rs.145

                                      therefore cost of 3 pizzas = 3×145

                                                                                  =435

                                         cost of 3 pizzas - Rs.435

similarly ,

  6 pastries costs--------> Rs.210

   1 pastry costs ----------> Y             now cross multiply to find Y,

      ⇒ 6Y=210

      ⇒ Y=35       ie, cost of one pastry is Rs.35

                          therefore cost of 12 pastries = 12 × 35

                                                                          = 420

                               cost of 12 pastries - Rs.420

totally for 3 pizzas and 12 pastries amount to be paid = Rs 435 + Rs 420

                                                                                         = Rs 855
