Given:10 mencan build a wall in5 daysToFind:Solution:Now,5menxTable:[tex]\begin{gathered}\begin{gathered}\begin{gathered} \tiny\boxed{\begin{array}{ c |c} \frak{ \pmb{men}}& \rm{ \pmb{days}}\\ \dfrac{\qquad\qquad}{ \sf 10}&\dfrac{\qquad\qquad}{ \sf 5 \: days}& \\ \dfrac{\qquad\qquad}{ \sf 5}& \dfrac{\qquad\qquad}{ \sf x \: days} \end{array}}\end{gathered}& \\ \end{gathered}\end{gathered}[/tex]

Here,inverse proportionWhen,[tex] \longrightarrow \tt \: 10 : 5 \propto 5 : x \\ \\ \\ \longrightarrow \tt \: 50 = 5x \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \longrightarrow \tt \: x = \cancel \frac{50}{5} \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \longrightarrow \tt { \boxed{ \frak{x = 10 \: days}}}[/tex]

Henceforth,5mencanbuildthewallin10daysMethod2Weknow,So,[tex] \longrightarrow \tt \: 10 \times 5 \: days \\ \\ \\ \longrightarrow \: { \pink{ \boxed{ \tt{ 50 days}}}}\: \: \: \:[/tex]

Here,Correct Question :-If

10 mencan build a wall in5 days. Then inhow manydays5 mencan build the same wal?Given:10 mencan build a wall in5 days.Tofind:5 mencan build he same wall?Solution:• Let’s consider

daysRequired for5 mento build the same wall bex.10,5,5&xare given to us.What to do?We need to find

x.Step-by-step explanation :-Here,

10 mencan build a wall in5 days. We have to find outx(how many days5 mencan build the same wall).→

10 : 5 = x : 5→ 10/5 = x/5

→ 5x = 5 × 10

→ 5x = 50

→ x = 50/5

→

x = 10∴ Hence,

5 mencan build the same wall in10 days.
