Mark the incorrect option.a)One-third of 12 is 4.b)3.337 = 3.34c)Area ...
Use option elimination here.
(1) = 12/3 = 4
2) 3.337 is equivalent to 3.34 but not equal to 3.34.
Hence, (2) is the correct choice for the question.
3) Area of square of side 10 cm = 102 = 100 cm2
Area of rectangle = 12.5 * 8 = 100 cm2
So, areas are equal.
4) 3348 m = 3 km 348 m
(1) = 12/3 = 4
2) 3.337 is equivalent to 3.34 but not equal to 3.34.
Hence, (2) is the correct choice for the question.
3) Area of square of side 10 cm = 102 = 100 cm2
Area of rectangle = 12.5 * 8 = 100 cm2
So, areas are equal.
4) 3348 m = 3 km 348 m

Mark the incorrect option.a)One-third of 12 is 4.b)3.337 = 3.34c)Area ...
Understanding the Incorrect Option
The correct answer is option 'B', and here's why it's incorrect:
Comparison of Values
- 3.337 is not equal to 3.34.
- The number 3.337 has three decimal places, while 3.34 has only two.
- When rounding 3.337 to two decimal places, it would round up to 3.34, but they are not inherently equal.
Analysis of Other Options
- Option A: One-third of 12 is indeed 4.
- Calculation: 12 ÷ 3 = 4.
- Option C: The area of a square with side 10 cm is equal to the area of a rectangle with length 12.5 cm and breadth 8 cm.
- Area of square: 10 cm x 10 cm = 100 cm².
- Area of rectangle: 12.5 cm x 8 cm = 100 cm².
- Option D: 3348 m is correctly converted to kilometers and meters as 3 km 348 m.
- 1000 m = 1 km, so 3348 m = 3 km + 348 m.
Conclusion
In summary, option 'B' is incorrect because it misrepresents the equality of decimal values. Understanding decimal places is crucial for accurate mathematical comparisons.
