If 70 men make a 98 m long wall in 6 days
Let the required length be x m.
More men, More length (Direct proportion)
Less days, Less length (Direct proportion)
Men 70:40
:: 98 : x
Days 6 : 12
Therefore, (70×6×x)=(40×12×98 )
x=(40×12×98 )/70×6= 112m
answer is 112 m
Let the required length be x m.
More men, More length (Direct proportion)
Less days, Less length (Direct proportion)
Men 70:40
:: 98 : x
Days 6 : 12
Therefore, (70×6×x)=(40×12×98 )
x=(40×12×98 )/70×6= 112m
answer is 112 m
