The length of River Ganga is 3255 km. When rounded off to the nearest hundred, its length will be:
Answer: Option D
:
D
When we round off a number to the nearest 100, we checkthe last two digits of the number. If the last two digits form a numberless than 50, we round down the number to the nearest lower multiple of 100.If the last two digits form50 or morethan 50, we round upthe number to the nearest highermultiple of 100.
Since the number 3255 has to be rounded off to the nearest hundred, our options are 3200 or 3300. 55 >50.
Hence the length of River Ganga when rounded off to the nearest hundred will be 3300 km.
