Let the total money Mr. Kale has be 10

ATQ,

His income increased by 30%

So, his total income now is 130

Now, total expenditure = 75 + 40% of 100

= 75+40=70

Now, total money he saves = 130-115

= 15

So, % he saves of his earning = 15/130 * 100

150/13

12%

So, he saves 12% of his income.

Hope this helps.

Answer 2

Let income = 100 Rs

expenditure= 75% of 100 rs = 75 rs

therefore, saving = 25 rs

new income= 130% of 100 =130 rs

new expenditure= 140% of earlier

expenditure= 140% of 75= 105 rs

So, new savings= 130-105= 25 rs.

Percentage of his earnings he saves

= 25/130 × 100= 19.2% (approx)
