If the zeros are significant figures then 900 is correct to 3 significant figures. If rounding off has occurred then the answer could be 1 sf or 2sf. For example : If the original number was 903 and rounding off to the nearest ten was required then 900 is correct to 2 significant figures. If the number was 927 and rounding off to the nearest hundred was required then 900 is correct to 1 significant figure.
To express 1602 to 2 significant figures, you identify the first two non-zero digits, which are 1 and 6. Rounding the number, it becomes 1600. Thus, 1602 correct to 2 significant figures is 1.6 × 10^3.
The correct answer is 2. The three zeros between the decimal point and the 1 are place holders but they are NOT significant digits. See, for example, the Wikipedia link.
