hours are same
you should only consider days

Answer 6

yep ! just get everything into `men` maybe

Answer 7

work of 3men=5 boys
work of 5 men=\[\frac{ 5 }{ 3}\times 5=\frac{ 25 }{ 3 } boys\]
work of 5 men+7 boys=\[\frac{ 25 }{ 3 }+7=\frac{ 25+21 }{ 3 }=\frac{ 46 }{ 3 } boys\]
again work of 9 men\[\frac{ 5 }{ 3 }\times 9=15 boys\]
work of 9 men +8 boys=15+8=23 boys

Answer 8

\[\frac{ 46 }{ 3 }~boys~ working~ 10 ~hrs~complete ~work~\in~days=24 \]
\[23~boys~working~10~hrs~will~complete~work=24\times \frac{ 46 }{ 3 }\times \frac{ 1 }{ 23 }=?\]
