Answer:
Base 10 Number System = (0,1,2,3,4,5,6,7,8,9)
In a Carton of table tennis there are 10 boxes.
And Each Box can Hold 10 Balls.and if i mark boxes from 0 to 9, then
then there are 10 boxes , Total number of Balls=100
So if I represent a single Carton by A, then
A[single carton] ={0,1,2,3,4,5,6,7,8,9}= 10 boxes =100 balls
B [2 carton]= 20 boxes=200 balls
C[ 5 cartons + 3 Boxes] = 5× 100+ 3×10 =530 balls
D[ 12 cartons + 8 Boxes]= 12×100+8×10=1280 balls
Now you can see,
Each carton is holding the balls in decimal number system.
Boxes = Ten's place in number system,
Number of cartons = either Hundred place or thousand place or more than that
In this way we can represent Carton and Box for table tennis balls in decimal number system having base 10 .
