Question

There are 23 green fields and 21 yellow fields. Select the correct option that finds the total number of fields.

• A. Method 1
  
• B. Both the methods are incorrect.
  
• C. Method 2
  
• D. Both the methods are correct.
  

Answer 1

The correct option is A Method 1


Detailed step-by-step solution:
In Method 2, 21 is incorrectly broken apart as 10 and 12. The correct equation should be 21 = 10 + 11.

Method 1 shows the correct decomposition.
The total number of fields is 44.

44 has 4 Tens and 4 Ones.

Tens	Ones

Hence, Option A is correct.
