Answer 1

Answer:

40 percent is the answer of your questions

Answer 2

Answer:

30%

Step-by-step explanation:

He spends 60% of his income. So, expenditure  E1=60x , [savings  S1=40x ]

His income increases by 15%. So, new income,  I2=115x  

Expenditure increases by 5%. So, 5% increase on  60x  results in new expenditure  E2=63x  

So, new savings  S2=115x−63x=52x  

So, percentage change in savings can be calculated as:

=52x−40x40x×10  

=30%
