The demand of a product over 6 weeks in 90, 110, 105, 130, 85 and 102 per week. If the average of last 3 weeks demand in x and that of last 5 weeks in y then $x+y $ (to the two decimal ) is :
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 212.07
Weakly Demand of a Product over 6 weeks -
90, 110, 105, 130, 85, 102
$x$, Average of last 3 weeks = $\frac{130+85+102}{3}$
$=105.67$
$y$, Average of last 5 weeks = $\frac{110+105+130+85+102}{5}$
$=106.40$
$∴x+y=212.07$
