Answer 2

Given: Initial rent of house = ₹ 250

            New rent of house = ₹ 300

To Find: Percent increase in rent.

Solution:

Increase in rent = New rent - Initial rent

                          = ₹ ( 300 - 250)

                          = ₹ 50

Let the initial rent be 'x,' and the increase in rent be 'δx.'

∴ Percentage increase in rent = $\frac{\delta x}{x} \times 100 %$ %

                                                  = $\frac{50}{250}\times 100$ %

                                                  = 20%

Answer: The percentage increase in rent is 20 %.
