The salaries of X, Y, and Z are in the ratio 10 : 20 : 20. If the increments of 82%, 50%, and 19% are allowed respectively in their salaries, what will be the new ratio of their salaries?​

Correct option is B

Given:

Initial Salary Ratio = X : Y : Z = 10 : 20 : 20

Increments:

X = 82%, Y = 50%, Z = 19%

Formula Used:

New Salary = Old Salary × (1 + Percentage Increase/100)

Solution:

X's new salary = $$10 × (1 + \frac{82}{100}) = 10 × 1.82 = 18.2$$​​

Y's new salary = $$20 × (1 + \frac{50}{100}) = 20 × 1.5 = 30$$​​

Z's new salary = $$20 × (1 + \frac{19}{100}) = 20 × 1.19 = 23.8$$​​

New Salary Ratio = 18.2 : 30 : 23.8

Simplified Ratio = 91 : 150 : 119
