Question

a person spends 75% of his income if his income increases by 20% inexpensive increased by 15% find then find the percentage increase in his savings​

Answer 1

Answer:

50%

Step-by-step explanation:

Let his income be Rs. 100 Expenditure = Rs. 75

Now Income is increased by 20%

Thus, new income =120

Expenditure is increased by 10% = 75 × $\frac{110}{100}$

= Rs. 82.50

Saving =120−82.50=37.50

Earlier saving =100−75=25

Increase in saving = $\frac{37.5 - 25}{25}$ * 100

= 505
