The hourly pay before the increase for marta and khalid is 21 and 17.5.
Given:
the ratio of martas hourly pay to khalids hourly pay is 6:5 both marta and Khalid get an increase of 1.50 in their hourly pay The ratio of Martas hourly pay to Khalid hourly pay after this increase is 13:11
Let x and y be the hourly pay before increase
x/y = 6/5
x = 6/5*y
x + 1.50 / y + 1.50 = 13/11
11(x+1.50) = 13(y+1.50)
11x + 16.5 = 13y + 19.5
11(6/5*y) = 13y + 19.5 - 16.5
66y/5 = 13y + 3.5
66y - 13*5y / 5 = 3.5
66y - 65y = 17.5
y = 17.5
x = 6/5*17.5
= 105/5
x = 21
