Question

The length of Car A is given as:

If the place value of 9 in the length of Car A is 100 times the place value of 9 in the length of another Car B, find the length of the Car B.

• A. 2091 inches
• B. 9085 inches
• C. 2509 inches
• D. 3944 inches

Answer 1

The correct option is C 2509 inches

In case of first option:
Length of Car A = 1903 inches
Length of Car B will be = 2091 inches
On comparing through a place value chart, we get:
So, the place value of 9 in the length of Car A is only 10 times that of place value of 9 in case of Car B.
∴ First option is incorrect.

Similarly, in case of second option:
Length of Car A = 1903 inches
Length of Car B will be = 9085 inches
On comparing through a place value chart, we get:
So, the place value of 9 in the length measurement of Car A is only $\frac{1}{10}$ times that of place value of 9 in case of Car B.
∴ Second option is incorrect.

In case of third option:
Length of Car A = 1903 inches
Length of Car B will be = 2509 inches
On comparing through a place value chart, we get:
So, the place value of 9 in the length measurement of Car A is 100 times that of place value of 9 in case of Car B.
∴ Third option is correct.

Finally, in case of fourth option:
Length of Car A = 1903 inches
Length of Car B will be = 3944 inches
On comparing through a place value chart, we get:
So, the place value of 9 in the length measurement of Car B is same as that of place value of 9 in case of Car A.
∴ Fourth option is incorrect.

Hence, the length of the Car B is 2509 inches.
