previous salary.
please get step by step answer ​

Answer 1

Answer:

Rs 130000

Step-by-step explanation:

Let original salary = Rs X

THEN

$x(1 + \frac{20}{100} ) = 156000 \\ x \times \frac{120}{100} = 156000 \\ x = 156000 \times 100 \div 120 \\ x = 130000 \\ \\ therefore \: \: \:p revious \: salary \: = 130000$

Answer 2

Let the original salary be x.

New salary = x + 20% of x.

= x + 20x/100

= x + x/5

= 5x/5 + x/5

= 6x/5

Therefore,

=> 156000 = 6x/5

=> 156000 × 5 = 6x

=> 780000 = 6x

=> 780000/6 = x

=> x = 130000

His original salary was rs. 130000
