The correct option is
D Both (a) and (b) above.
The two multiples of 100 between which 5,674 lies are 5,600 and 5,700.
From the place value diagram,
Digit at tens place is 7 which is more than 5.
∵ 7 > 5, the number will be closer to the higher multiple.
So, we will convert the digit at tens place and ones place to zero and add 1 to the digit at hundreds place.
∴ 5674 rounded off to the nearest hundreds will be 5700.
So, to round off 5,674 racing cars to its nearest hundreds, we have to convert the digits at ones place and tens place to zero.
Thus, both 7 and 4 have to be converted to 0.
