Question

12 : 30 :: 10 : x Find the value of x​

Answer 1

Answer:

X = 25

12 : 30 : : 10 : x

12 * x = 10 * 30

X = 300 / 12

X = 25

Hence the value of x is 25.

Answer 2

$\huge{\mathfrak{\underline{\underline{\purple{Solution:}}}}}$

${\bold{\underline{Given:}}}$

12 : 30 : : 10 : $x$

${\bold{\underline{To \: find:}}}$

The value of $x$

$\bold{\underline{Solved \: Answer:}}$

${⟹12 : 30 : : 10 : x}$

${\fbox{\sf{Product \: of \: extremes = Product \: of \: means}}}$

${⟹12 × x = 30 × 10}$

$⟹x = \frac{30 \times 10}{12}$

$⟹x = \frac{300}{12}$

$⟹x = 25$

$\bold{\underline{Final \: Answer:}}$

$\sf{12 : 30 : : 10 : 25}$
