Solution:

Total number of females working in a factory F1 = 280 + 262 + 314 + 328 + 336 + 444 = 1964
⇒ The average number of females working per day in a factory F1 =

{\Total \number \of \females \working \in \a \factory \F1}/{\Number \of \days}

⇒ The average number of females working per day in a factory F1 =

1964/6=327.33

⇒ Total number of females working in a factory F2 = 186 + 212 + 224 + 232 + 285 + 272 = 1411
⇒ The average number of females working per day in a factory F2 =

1411/6=235.16

⇒ The difference, in the average number of factory F1 and factory F2 = 327.33 – 235.16 = 92.17
∴ The difference is 92.17 in the average number of factory F1 and factory F2.
