Question:-

Find the value of x in each of the following

42 : 12 ::7: x

Answer:-

• The value of x is 2.

Solution:-

$\large{ \tt : \implies \: \: \: \: \: {}42 : 12 : : 7 : x}$

$\large{ \tt : \implies \: \: \: \: \: {}42 \times x = 7 \times 12}$

$\large{ \tt : \implies \: \: \: \: \: {}x = \frac{7 \times 12}{42} }$

$\large{ \tt : \implies \: \: \: \: \: {}x = 2}$
