Question

7. A man spends 20% of his monthly salary on food and deposits 25% of the
remaining in his bank account. If 480 is still left with him, calculate his monthly
salary.​

Answer 1

Answer:

$20 - 25x480$

Answer 2

Step-by-step explanation:

Let’s say his monthly income is x.

His expenses are:

Rent= 25% of x = .25x

Food= 30% of x = .30x

Other= 20% of x = .20x

Hence his total expense = .25x + .30x. + .20x = .75x.

His saving = Income - expense = x - .75x = .25x

So, .25x =15000

x = 15000 /.25 = 15000×100 / 25 = 60000

Hence Bobby,s monthly income is Rs 60000
