उत्तर
Weight of the parcel = 230 g
Cost of a parcel weighing 50 g or less = Rs 5
If the weight of the parcel is more than 50 g, then the cost for every additional 50 g is Rs 3.
Now, weight of the parcel = 230 g = 50 g + 50 g + 50 g + 50 g + 30 g
∴ Cost of the stamps = Rs 5 + Rs 3 + Rs 3 + Rs 3 + Rs 3 = Rs 17
So, the total cost of sending the parcel of 230 g is Rs 17.
Parcel weight = 230 g
Cost of stamps = Rs 17
