Answer 1

Given: $6:x::42:49$

we have to find the value of $x.$

This problem is solved in the following way;

$=>\frac{6}{x} =\frac{42}{49} \\\\=>\frac{6}{x}=\frac{6}{7} \\\\=>6=\frac{6}{7} *x\\\\=>\frac{6*7}{6} =x\\\\\\=>x=7$

Hence, the value of$x$ will be$7$.

Answer 2

Given that:- $6: x :: 42 : 49,$

To find:- The unknown value of 'x'
