Question

A man spends 2/3rd of his in-
come. If his income 'increases by 14% and the expenditure in-
creases by 20%, then the per-
centage increase in his savings will be​

Answer 1

Answer:

2%

Step-by-step explanation:

Let the income of the man be Rs 100.

 Expenditure = 2/3 of 100

                   = (200/3)

Saving = income - spends

            = 100 - 200/3

            = 100/3

If the income increases by 14%, expenditure(spend) increases by 20%

If  income = 100(1 + 14/100)

                 = 114

   Expenditure = (200/3) (1 + 20/100)

                         = 80

Savings = 114 - 80

             = 34

% increase in savings =

          = (final - initial)/initial  * 100%

          = (34 - 100/3)/(100/3)  * 100%

          = (2/3)/(100/3)  * 100%

           = 2%

Given:-

• A man spends 2/3rd of his income.If hid income increased by 14%a and the expenditure increased by 20%

To find :-

• The percentage increase in his savings will be ,

Explanation :-

• Now let, income of man=Rs.100
• Expenditure =2/3rd of 100
• Expenditure =200/3.

Now ,

• Savings= income-spends
• =100-200/3
• =100/3

Income =100 (1+14/100)

=114..

Now,

• Expenditure = (200/3)(1+20/100)
• Expenditure =80

At the last,

• %savings income =Final-initial /initial×100%
• %Savings income = 34-100/3/100/3×100%
• %Savings income =(2/3)(100/3)×100%
• %Savings income =2%.
