Figure for BBA-DBE Bangalore 2024 Slot 1 QA question 1 (Data Interpretation)

The number of female candidates in institution Y is:

310

355

425

400

✅ Correct Option: 2

Total students $= 5500$ , so $1\% = 55$ students.

Pie chart gives the total students (male + female) of each institute. Radar graph gives only the male students.

Total students in Y $= 21\%$ of $5500$

$= 21 \times 55$

$= 1155$

Male students in Y (radar graph) $= 800$

Female students in Y $=$ total $-$ male
