The number of candidates appearing for the exam from City C is what per cent of the number of candidates appearing for the exam from City B? (rounded to nearest integer)

$$\eqalign{ & \text{No. of candidates from city C} \cr & = 1.08\times100000 \cr & = 108000 \cr & \text{No. of candidates from city B} \cr & = 3.14\times100000 \cr & = 314000 \cr & \therefore \text{Required percentage} \cr & = \left(\frac{108000}{314000}\times100\right)\% \cr & = \left(\frac{108}{314}\times100\right)\% \cr & = \left(\frac{54}{157}\times100\right)\% \cr & = \frac{5400}{157}\% \cr & = 34.39\% \cr & \approx 34\% \cr} $$
