Answer 2

Answer:

24 men are needed to dig a 90ft ditch in half day

Step-by-step explanation:

Given that,

No.of men required to dig a 180ft ditch=8men

No.of Days required to dig a 180ft ditch=3days

Therefore,

8 men will dig a 90ft ditch in

$3 \times \frac{90}{180} days \: = 1.5 \: days$

We know that 8 men are required to dig a 90ft ditch in 1.5days.Therefore,no.of men required to dig 90ft ditch in half day are,

$8 \times \frac{1.5}{0.5} = 8 \times 3 = 24 \: days$

Therefore,24 men are needed to dig a 90ft ditch in half day
