Question

Anand's income and expenditure are in the ratio of 9:5 find the central angle of the sector,which represents Anand's savings​

Answer 1

The central angle of the sector, which represents Anand's savings will be 160°.

Step-by-step explanation:

Given that, Anand's income and expenditure are in the ratio of 9:5.

Now, if Anand's income is 9x then his expenditure will be 5x.

So, his savings will be (9x - 5x) = 4x.

If the total sector i.e. 360°  central angle represents the total income, then the central angle of the sector, which represents Anand's savings will be

$\frac{360}{9} \times 4 = 160^{\circ}$. (Answer)
