Correct Answer - Option 4 : 2090
Calculation:
Total number of students Appeared in exam from the Zone-K in all the six years = 782 + 804 + 720 + 750 + 824 + 850 = 4730
Total number of students Passed in exam from the Zone-K in all the six years = 360 + 472 + 448 + 360 + 504 + 496 = 2640
Difference = 4730 – 2640 = 2090
∴ The required difference in the number of appeared to the passed students in the Zone-K is 2090
