Question

Match the given data to its average.

• A. 19
• B. 20
• C. 21

Answer 1

$\text{Average}=\frac{\text{Sum of all observations}}{\text{Total number of observations}}$

$\left(i\right)$ For given data 15, 25, 45, 10, 5,

$\text{Average}=\frac{15+25+45+10+5}{\text{5}}=\frac{100}{5}=20$

$\left(ii\right)$ For given data 11, 24, 7, 21, 32

$\text{Average}=\frac{11+24+7+21+32}{\text{5}}=\frac{95}{5}=19$

$\left(iii\right)$ For given data 14, 44, 13, 22, 12,

$\text{Average}=\frac{14+44+13+22+12}{\text{5}}=\frac{105}{5}=21$
