To round to 3 significant figures, count 3 digits starting from the first non-zero digit. The first three digits are 3, 1, and 4, giving us 3.14. Now look at the fourth digit (1). According to rounding rules, if the next digit is less than 5, we round down (keep the number as is). Since 1 < 5, we keep 3.14. This question type is common in ECZ Paper 1, where precision and accuracy are tested.
