Question

the salary of A man has increased by 20% . if he now gets 3000. his salary before the increase by​

Answer 1

Answer:

let the salary before he got be X

his new salary is 3000

if the old salary is 20% increase then it is now the new salary 3000

X + 20% of X = 3000

X +( 20 × X/100 ) = 3000

X + (X/5) = 3000

6X/5 = 3000

6X = 3000×5

X = 1500/6

therefore, X = 250

Answer 2

Salary of a man before the increment of 20 % is 2500 rupees.

Step-by-step explanation:

Given Data

Salary of a man increased by 20 %

After the increment his salary is 3000 rupees

Find the salary before the increment

Let us consider the salary as ' x '

And consider the salary after increment as x + 20 %

Then the equation can be written as,

x + 20 % of x = 3000

x + $\frac{20}{100}$ (x) = 3000

x (1 + $\frac{20}{100}$) = 3000

x ( 1 + $\frac{1}{5}$) = 3000

x ($\frac{5+1}{5}$) = 3000

$x \frac{6}{5} = 3000$

6 x = 3000 × 5

6 x = 15000

$x = \frac{15000}{6}$

x = 2500

Therefore the salary of a man increased by 20 % and  he gets 3000 now, then the salary of a man before the increment is 2500 rupees.
