Question

Divide 84 into two parts such that one upon two of one part is equals to 1 upon 3 of the other part

Answer 1

$\boxed{ \bold{ \underline{ \: let \: parts \: are \: x \: and \: (84 - x)}}}$






$\bold{ \underline {According \: to \: the \: question : \: }}$


$\frac{1}{2} \times x = \frac{1}{3} (84 - x) \\ \\ \\ 3x = 2(84 - x )\\ \\ 3x = 168 - 2x \\ \\ 5x = 168 \\ \\ x = \frac{168}{5}$




$\boxed{\bold{ \: \underline{Parts : }}}$



168 / 5

2): 84 - 168 / 5

=> ( 420 - 168 ) / 5

=> 242 / 5
