Answer:
1700, 3517, 1573, 7351
Step-by-step explanation:
1735 ≈ 1700 [ 35 is less than 50 so after round off 35 will be considered as 00]
3517 ≈ 3500 [Since 17 is less than 50 therefore, after round off 3517 will become 3500]
1573 ≈ 1600 [73 is more fifty so it will be considered as 100 as a whole number and 1573 will become 1600 ]
7400 ≈ 7351 [Since 51 is greater than 50 so it will be considered as 100 and 7351 will become 7400 after round off]
