Correct Answer - Option 1 : 334

**Calculation:**

The total number of candidates who appeared for an interview over the six years in Aerospace = 1180 + 1260 + 1132 + 1060 + 1465 + 1640 = 7737

The total number of candidates who appeared for an interview over the six years in Electrical = 1216 + 1132 + 1260 + 1191 + 1242 + 1362 = 7403

Difference = 7737 – 7403 = 334

**∴ The required difference of the candidates in Aerospace and Electrical Engineering is 334**
