Answer
(i) 5706
The digit at hundreds place is 7. Since 7 is greater than 5, we increase the digit at thousands place by 1 and replace each of the digits at hundreds, tens and ones place by 0.
Hence, the rounded off number to the nearest thousands = 6,000.
(ii) 378
The digit at hundreds place is 3. Since 3 is less than 5, we replace each of the digits at hundreds, tens and ones place by 0.
Hence, the rounded off number to the nearest thousands = 0.
(iii) 47,599
The digit at hundreds place is 5. So, we increase the digit at thousands place by 1 and replace each of the digits at hundreds, tens and ones place by 0.
Hence, the rounded off number to the nearest thousands = 48,000.
(iv) 1,09,736
The digit at hundreds place is 7. Since 7 is greater than 5, we increase the digit at thousands place by 1 and replace each of the digits at hundreds, tens and ones place by 0.
Hence, the rounded off number to the nearest thousands = 1,10,000.
