Question

Sam receives a salary of $X in his salary account. He deposits 20% of 25% of 30% of X into his
savings account. How much salary (in $) did Sam receive if the amount deposited by him in his
savings account is $750?​

Answer 1

Answer:

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

Answer 2

Given :

saving accounts = $750

expenses = 20% , 25% & 30%

To find:

Sam's Salary

Step-by-step explanation:

Let expenses are(in $):

Rent= 25% of x = $0.25x$

Food= 30% of x =$0.30x$

Other= 20% of x = $0.20x$

Hence his total expense = $0.25x + 0.30x. + 0.20x = 0.75x.$

His saving = Income - expense =$x - 0.75x = 0.25x$

So, $0.25x =15000$

x = $\frac{15000}{0.25} = \frac{15000*100}{25} = 60000$

Hence Bobby's monthly income is  $60000
