If the income of x is 10% more than that of y and the income of y is 20% less than that of z, then the income of x, y and z respectively are in the ratio -

Correct option is C

Let the income of z = 100
Then, Income of y = 100 × 80/100 = 80
Then, Income of x = 80 × 110/100 = 88
Required ratio of x, y and z = 88:80:100
Required ratio of x, y and z = 22:20:25
