Answer:
Step-by-step explanation:
20 men - 8 days - 1/4 work =
? men - 4 days - 3/4 work
Answer :
20 men - 8 days - 1/4 work =
20 men - 8*3 days - 1/4*3 work =
20 men - 24 days - 3/4 work =
20*2 men - 24/2 days - 3/4 work =
40 men - 12 days - 3/4 work =
40*3 men - 12/3 days - 3/4 work =
120 men - 4 days - 3/4 work =
There already are 20 men so,
120 - 20 = 100
So, more 100 men are needed to achieve the target.
