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​

Answer 1

Answer:

• Average : Average is defined as a value found by adding all of the numbers in a set together and then dividing them by the quantity.

$\rule{100}{1}$

$\underline{\bigstar\:\:\textsf{According to the Question :}}$

$:\implies\sf Average=\frac{Sum\:of\:the\:Terms}{Number\:of\:the\:Terms}$

⠀

$:\implies\sf Average=\frac{(105+216+322+167+273+405+346)}{7}$

⠀

$:\implies\sf Average=\dfrac{1834}{7}$

⠀

$:\implies\underline{\boxed{\sf Average=262}}$

⠀

$\therefore\:\underline{\textsf{Average No. of Coupon Issued is \textbf{262}}}.$

Answer 2

Given

• Number of coupons per day issued:

→ 105, 216, 322, 167, 273, 405 & 346.

To find

• Average number of coupons issued per day

Solution

As we know,

→ Average = (Sum of observations)/(Number of observations)

Here,

⇒ Number of observations = 7

AccordinG to Question :

⇒ Average = (105 + 216 + 322 + 167 + 273 + 405 + 346)/7

⇒ 1834/7

⇒ 262

Therefore,

∴ Average number of observations issued per day = 262 .

Additional informations:-

• Range = (Larger number - Smaller number) + 1
• Median = [(n/2) + (n/2 + 1)]/2 th [If n = even number ]
• Median = (n + 1)/2 th [If n = odd number]
