ans.12%

Answer 2

Answer:

40%

Step-by-step explanation:

we take income is income1=100

and income increased by 26%

income2= 100+(26÷100)×100=126

expenditure1= 70%

savings1 = income1- expenditure1 = 100-70 =30%

the monthly income increased by 20%.

100+(20=100)×100=120

the expenditure which is 70% of his monthly income increased by 20%.

Expenditure2 =(70÷100)×120=84

savings2= income2- expenditure2

= 126 - 84 = 42

savings increased by percentage

(savings2 - savings1 ÷ savings1)×100

(42 - 30 ÷ 30) ×100 = 40%
