$i.\ $Production was maximum in the $2^{nd}$ week.
$ii.\ $Prodction was minimum in the $4th$ week.
$iii.\ $Average production of these five weeks $=\frac{\text{Total production of all weeks}}{\text{Number of weeks}}$
$=\frac{1000+600+800+500+700}{5}$
$=\frac{3600}{5}$
$=720$
$iv.\ $Number of cycles produced in the first $3$ week $= ($Production in the $1^{st}$ week $+$ Production in the $2^{nd}$ week $+$ Production in the $3^{rd}$ week$)$
$=600+1000+800$
$2400\ \text{cycles}$
$ii.\ $Prodction was minimum in the $4th$ week.
