​

Answer 1

Answer:

Step-by-step explanation:

WE KNOW,

INCOME = EXPENDITURE + SAVING

87.5% = 7/8 THEN,

8= 7+1

HIS INCOME INCREASE (100/9%= 1/9)

For easy claculation multiple b.s by 9

8×9= 7×9 + 1×9

Now for increasing their income and expenditure (14.28%=1/7) then ,

80=72 + 8

Now for saving % we know

Saving%= saving / income % = 8/80% = 10% so ans is 10%
