Correct Answer: 100 fans
Solution :
According to the provided bar graph,
Total number of table fans produced on Monday and Tuesday $= 260 + 540 = 800$
Number of days $= 2$
Average production of table fans on Monday and Tuesday $= \frac{\text{Total productivity on Monday and Tuesday}}{\text{Number of days}}=\frac{800}{2}=400$
Total production of table fans in the week $= 260+540+360+120+200+320 = 1800$
Required average production of table fans in the week $= \frac{1800}{6}=300$
The weekly average production is 300.
Required difference = Average production on Monday and Tuesday – Weekly average production $= 400 - 300 = 100$ fans
Hence, the correct answer is 100 fans.
