Detailed Explanation & Answer
The employees for office-D and office-E for all years:

Total for office-D = 240 + 224 + 248 + 270 + 236 + 258 = 1476

Total for office-E = 280 + 304 + 316 + 332 + 340 + 348 = 1920

Average for office-D = 1476 / 6 = 246
Average for office-E = 1920 / 6 = 320

Difference = Average for office-E - Average for office-D
Difference = 320 - 246 = 74
सभी वर्षों के लिए कार्यालय-D और कार्यालय-ई के कर्मचारी:

कार्यालय-D के लिए कुल = 240 + 224 + 248 + 270 + 236 + 258 = 1476

कार्यालय-E के लिए कुल = 280 + 304 + 316 + 332 + 340 + 348 = 1920

कार्यालय-D के लिए औसत = 1476/6 = 246
कार्यालय-E के लिए औसत = 1920/6 = 320

अंतर = कार्यालय-E के लिए औसत - कार्यालय-D के लिए औसत
अंतर = 320 - 246 = 74
