Answer 2

Answer:

Step-by-step explanation:

Kailash used to spend 85% of his income which means his earlier saving were 15%.

Let X be his earlier income.

then earlier savings, Si = 0.15 X

earlier spends, Spi = 0.85 X

Now, income increased by 40%, so new income = 1.4 X

current spends also increase by 40%, i.e. Sp_n = (0.85 X) * (1+0.4) = 1.19 X

% saving now, S_n = (1.4 X- 1.19 X) / (1.4 X) = 0.15 or 15%

So, he saves same percentage.
