Answer 1

Given:

Total income = Rs. 360000

The income of 2nd week making angle on the pie chart = 120°

Concept used:

The angle made in the centre of the circle is 360° or by one complete rotation is 360°

Here, Angle made at the centre is equal to Rs 360000

Calculations:

Angle made at the centre is equal to Rs 360000

⇒ 360° = 360000

⇒ 1° = 360000/360°

⇒ 120° = 120° × (360000/360°)

⇒ 120000

∴ The income of his 2nd week is Rs 120,000
