Answer 2

Answer:

23.077%

Step-by-step explanation:

let the original salary be x

increment of salary = 30% of x

new salary = x + 30x/100 = 13x/10

difference between new salary and original salary = 13x/10 - x = 3x/10

so, percentage = (3x/10 ÷ 13x/10)* 100 = (3/13)/100 = 300/13% = 23.077%(approx)
