(Ans. *500]
6/ Aman spends 9/10 of his monthly income on domestic affairs. He donates 30% of the balance​

Answer 1

Answer:

Step-by-step explanation:

Solution-

Consider X be Lovely's salary.

She saves 20% × X.

Hence expenditure = 80%×X

Due to dearness her expenses increased by 20%.

New expenses = 120%(80%X)

New expenses = 96% of X

Now her savings are

New savings = X - 96% X = 4% of X

But given is new savings = Rs.20

20 = 4% × X

X = 20×100/4

X = Rs.500
