Answer 1

Answer:

option C

Step-by-step explanation:

Let his Monthly salary =x

Food expenses =10020×x=5x

House Rent =10040×(x−5x)=58x

Remaining amount

=x−5x−258x=2525x−5x−8x=2512x

Hence, 2512x=5760

⇒x=12000 and yearly salary=12×12000=144000.

Hence, option C is the correct answer

With Lunchclub, we have created a way to network over video both locally and globally. Previously, I have built networks over the

Let's calculate :

Expenditure on food + Expenditure on house rent + Expenditure on Entertainment + Expenditure on conveyance = Monthly Expenditure

i.e. 40% + 20% + 10% + 10% = 80%

Therefore, Radha's monthly expenses are 80% of her salary.

i.e. 100% - Monthly expenses = Monthly saving

So, 100% - 80% = 20%

Hence, Radha saving is 20% of her Monthly Salary … (1)

Radha's saving at the end of the month is 1500 rupees … ( given)(2)

So, Radha's Monthly Saving is 20%(from point 1) and her Monthly Saving is 1500( from point 2)

1500 rupees is 20% saving of Radha's Monthly Salary so 10% saving of Radha's salary is 750 rupees

i.e. 10% of Radha's Monthly saving × 10 = Radha's Monthly Salary.

750 × 10 = 7500 rupees

Therefore Radha's Monthly Salary is 7500 rupees.

Radha spends 40% of her salary on food, 20% on house rent, 10% on entertainment and 10% on conveyance. If her savings at the end of the month are Rs 1500, then what is her monthly salary?

Well, the answer is not that difficult to find.

40 + 20 + 10 + 10 = 80% is the total money spent by Radha.

That leaves 20% which equals Rs 1500.

Let us say her salary is Rs x.

Thus, 20% of x = 1500, or

20x/100 = 1500, or

x = 1500 x 100 / 20

which gives us ,

x = Rs 7,500.

Which is your answer.
