15000 Rs

Answer 2

Answer:

x = Rs.15000

Step-by-step explanation:

let the initial salary , S = Rs.x

rate of increment = 20%

=> the increment = 20x/100

salary after increment = Rs 18000

ie., x + (20x/100) = 18000

=> (100x+20x) / 100 = 18000

=> 120x  = 18000 * 100

=> x = (18000 * 100)  / 120

=> x = 150*100

=> x = Rs.15000
