Question

if 21 men can construct a road in 90 hours how many men are needed to construct the same road in 70 days​

Answer 1

Answer:

16

Step-by-step explanation:

Number of men required to construct a road in 90 hours= 21

so, Number of men required to construct a road in 1 hour= 21/90

hence, Number of men required to construct a road in 70 hours=(21/90)*70=16.33=16(approx.)
