Question

If the mean 17,19,23,16,a, 18 and 14 is17. Find the value of a

Answer 1

$\huge\mathbb{\red{SOLUTION:-}}$

$\huge {\sf{To\:find:-}}$

• We have to find the value of a

Now :-

$\boxed{\sf{Mean=\frac{sum\:of\: observation}{Number\:of\: observation}}}$

$\bf\underline{\red{According\:To\: Question:-}}$

$\sf\implies \frac{17+19+23+16+a+18+14}{7}=17\\ \\ \sf\implies 107+a=119\\ \\ \sf\implies a=119-107\\ \\ \sf\implies a=12$

• The value of a is 12

$\huge\underline{\boxed{\red{\mathfrak{a=12}}}}$
