Q9Tom bought 12 liter of coke. He served it to 2 people. Which of the following figures represent the amount of coke that each of them got?

A. Figure 2
B. Figure 4
C. Figure 3
D. Figure 1

Solutions
Share 
Step: 1
A square represents 1 whole (1 liter of coke).
Step: 2
Divide the square vertically into 2 equal parts. Each part represents 12 liter of Coke.
Step: 3
Again divide the square into 2 horizontal sections.
  [Since the coke is to be shared by 2 persons.]

Step: 4
We get a total of 4 parts. One part out of a total of 4 parts i.e., 14 liters is what each person got. Thus 12 liter is divided into 2 equal parts of 14 liter each.
Correct Answer is :   Figure 3
