Solution plzzzzzzzzzzzzzzzzzzzzzzzzzzz answer step by step​

Answer 1

Answer:25000

Step-by-step explanation:

Let the monthly income be x when the expenditure is 20000

So 20000/16000=x/20000

x=25000

Answer 2

The monthly income of the person is Rs.25,000.

Given,

Old monthly income = Rs.20,000

Old expenditure = Rs.16,000

New expenditure = Rs.20,000

To Find,

New monthly income.

Solution,

Let's find the ratio of monthly income to monthly Expenditure.

Monthly income = Rs.20,000

Monthly expenditure = Rs.16,000.

So,

The ratio of Monthly income to Monthly expenditure = 20,000:16,000

= 4:5.

Let the ratio of monthly income to monthly Expenditure be 4x and 5x.

x be the one unit of amount.

If new monthly expenditure = 20,000

then, the value of x is:

4x = 20,000

x = 5,000

So, the new income will be 5x

= 5 × 5,000

= 25,000.

The monthly income of the person is Rs.25,000.
