Question

. Suresh gets his salary credited to his bank account in the beginning of the month. He spends one-third of his salary on rent, and a sum of Rs.10,000 to purchase a new mobile phone. Of the amount left, he spends one-half on groceries and one-third on paying his bills. If the balance at the end of the month is Rs.2000, what is his salary?

Answer 1

Answer:

You can solve this question by assuming x at the place of his salary

Answer 2

A salary is a form of periodic payment from an employer to an employee, which may be specified in an employment contract. It is contrasted with piece wages, where each job, hour or other unit is paid separately, rather than on a periodic basis.

In banking and accounting, the balance is the amount of money owed on an account. In bookkeeping, “balance” is the difference between the sum of debit entries and the sum of credit entries entered into an account during a financial period. When total debits exceed total credits, the account indicates a debit balance.

Let the salary be $3x$

Salary spend on Rent $=\frac{1}{3} \times 3x=x$

Spend on mobile phone$=10000$

Amount left $= 3x-[x+10000]$

$=2x-10000$

Spend on groceries $=\frac{1}{2}[2x-10000]$

Paying the bills $=\frac{1}{3}[2x-10000]$

$=\frac{2x}{3}-\frac{10000}{3}$

Left $=2x-1000-(x-5000)-[\frac{2x}{3}-\frac{10000}{3} ]$

$=x-5000-[\frac{2x}{3}-\frac{10000}{3} ]$

$=x-5000-\frac{2x}{3}+\frac{10000}{3}$

$=\frac{x}{3}-\frac{5000}{3}$

Balance    $\frac{x}{3}-\frac{5000}{3}=2000$

$\frac{x}{3}=2000+\frac{5000}{3}=\frac{11000}{3}$

$\frac{x}{3}=\frac{11000}{3}$

$x=11000$

Salary $3x=3\times 11000$

$=33000$
