Answer 1

$\huge\bf{Question}$

The following is the list of number of coupons issued in a school canteen during a week:

105, 216, 322, 167, 273, 405 and 346.

Find the average no. of coupons issued per day.

Solution:

Number of coupons issued in a week : 105, 216, 322, 167, 273, 405 and 346.

So, we get,

Mean = sum of observation/ total no of observations

Mean = 106+ 215+ 323+166+273+405+346/ 7 = 346/7

Mean = 262

Answer 2

$= \frac{(105 + 216 + 322 + 167 + 273 + 405 + 346)}{7} \\ = \frac{1834}{7} \\ = 262$
