Option 3 : Statement I, II and III together are required

Le the total work be 100 units

Statement I:

Efficiency of amit and anand = 100/20 = 5

Statement II:

Efficiency of amit and sahil = 100/25 = 4

Statement III:

Adding result of statement I and II

Anand + sahil + 2 × amit = 9

We know,

efficiency of amit and anand is 2 : 3

3 + sahil + 2 × 2 = 9

⇒ Efficiency of sahil = 2

Efficiency of anand and sahil = 3 + 2 = 5

Number of days required = 100/5 = 20

Question can be answered using all statement together
