Answer 2

Given :

• Four labourers build a wall in 8 days.

To Find :

• How many days it takes to build the same wall by 16 labourers.

Solution :

★ Number of Labourers :

• x1 = 4
• x2 = 16

★ Number of Days :

• y1 = 8
• y2 = ?

Number of Labourers and Number of Days are indirectly proportion.

So, we've x1 = 4, x2 = 16, y1 = 8

⇒ x1 × y1 = x2 × y2

⇒ 4 × 8 = 16 × y2

⇒ 32 = 16 × y2

⇒ y2 = 32 / 16

⇒ y2 = 2

•°• It takes 2 days to build the same wall by 16 labourers.
