Question

Mrs. Sanchita earns 11000 per month. She spends 85% of the amount and saves the rest. On 1st January her salary was increased by 20%. She now increased her expenses to 87% of her salary. How much more or less does she save now? ​

Answer 1

Step-by-step explanation:

Mrs Sanchita earned Rs 11000 per month.

She spent 85% of the amount that is 85% of 11000 = (85/100)(11000) = Rs 9350.

So she saved Rs 11000-9350 = Rs1650.

Now on January 1st , her salary increased by 20%.

New salary = 11000+20%of 11000= 11000+(20/100)(11000) = 11000+2200 = Rs 13200

She spends 87% of new salary

It means she spends (87/100)(13200) = Rs 11484.

So she saves 13200-11484 = Rs 1716

So as compared to old salary (when she saved Rs 1650) she now saves Rs 1716

So she saves Rs 1716-1650 = Rs 66 more

Answer 2

$\pink{Sanchita\:earn = Rs. 11,000}$

$Money\:Spend = (\frac{85}{100}$)*11,000

$\:\:\:\:\:\:\:\:\:\:\:\:$$\red{=9,350}$

$\blue{Savings = 11,000-9,350}$

$\:\:\:\:\:\:\:$$\red{=1,650}$

Increase in salary = $(\frac{20}{100})$*11,000

$\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:$$\red{=11,484}$

$\blue{Saving = 13,200-11,484}$

$\:\:\:\:\:\:\:\:\:$$\red{=1,516}$

$\blue{less savings = 1,650-1,516}$

$\:\:\:\:\:\:\:\:\:\:$$\red{=134}$
