Answer 2

Her new saving is Rs. 12000.

Step-by-step explanation:

Since we have given that

Amount earned by her per month = Rs. 50,000

Percentage of spending = 80%

Expenditure becomes

$0.8\times 50000=40000$

Rate of increment = 20%

So, new income becomes

$\dfrac{100+20}{100}\times 50000\\\\=\dfrac{120}{100}\times 50000\\\\=120\times 500=60000$

So, expenditure is increased by 20%.

So, new expenditure becomes

$\dfrac{100+20}{100}\times 40000\\\\=\dfrac{120}{100}\times 40000\\\\=1.2\times 40000\\\\=48000$

So, new saving becomes

New income - new expenditure

$60000-48000=12000$

Hence, her new saving is Rs. 12000.
