Question

7. A person spends 75% of his income. If his income increases by 20% and expenses increase by 15% then find
the per cent increase in his savings.​

Answer 1

Answer:

5%

Step-by-step explanation:

Given: 75% of income spent.

25% savings.

Income increases by 20% then, Expenses increase by 15%. (equation 1)

Expenses = Money spent.

As per question,

Total Income = 100%

Applying 1 equation,

100 + 20 then 75 + 15

120 % income then 90 % expenses

Therefore, Saving percent = 120 - 90 = 30%

Current saving percent = 30%, Saving percent before increase = 25% (given).

Increase = 30 - 25 = 5%

Hope it Helps :D
