Answer 2

Given:

Find the value of x in 20:30::60:x​

Solution:

Evaluate $x$,

$\[\begin{array}{l} \Rightarrow \frac{{20}}{{30}} = \frac{{60}}{x}\\ \Rightarrow x = \frac{{60 \times 30}}{{20}}\\ \Rightarrow x = 3 \times 30\\ \Rightarrow x = 90\end{array}\]$

Hence, the required value of $x$ is 90.
