Question

if 15 men make 234m long wall then what is the length of wall made by35 men
​

Answer 1

$Number \:of \: men \: increases ,the \: length \\of \: the \: wall \:made \: increases .$

$Clearly , number \: of \:men \: directly \: varies\\with \:the \: length \: of \: the \: wall \: made$

$So, \frac{x_{1}}{y_{1}} = \frac{x_{2}}{y_{2}}\\</p><p>Here, \: x_{1} = 15 \: men, \: y_{1} = 234 \: m \\</p><p>x_{2} = 35 \: men, \: y_{2} = \red{?}\: m$

$By \: substituting , \\\frac{15}{234} = \frac{35}{y_{2}}$

$\implies y_{2} = 35 \times \frac{234}{15} \\= \frac{8190}{15} \\= 546 \:m$

Therefore.,

$\pink { 34 \: men \: make \: 546 \:m \: long \:wall }$
