Question

Hamid deposited 1/4 of his salary in a bank. Then he spent rupees 3000 and found that he was left with 7/12 of his salary. Find his salary.

Answer 1

total salary=x
deposited=x/4
spended=3000
remaining=7x/12
so,x=x/4+3000+7x/12
x=3x+36000+7x/12
12x=10x+36000
2x=36000
total salary=18000

Answer 2

Answer:

Rs. 18000

Step-by-step explanation:

Let the salary be x

He deposited $\frac{1}{4}$ of his salary

Amount deposited in account = $\frac{x}{4}$

Remaining amount =  $x-\frac{x}{4}=\frac{3x}{4}$

He spent 3000 rupees

Remaining amount = $\frac{3}{4}x - 3000$

Now he left with $\frac{7}{12}x$

$\frac{3}{4}x - 3000 = \frac{7}{12}x$

$\frac{3}{4}x - 3000 = \frac{7}{12}x$

$\frac{3}{4}x-\frac{7}{12}x=3000$

$\frac{9x-7x}{12}=3000$

$\frac{2x}{12}=3000$

$x=\frac{3000 \times 12 }{2}$

$x=18000$

His salary is Rs. 18000
