Answer:
Ratio of Quentin new income to Sam new income is
So option (a) will be correct option
Step-by-step explanation:
Let Rex income is 100
Then Paul income is 40 % less than Rex income 100 - 100×0.4 = 100-40 = 60
And Quentin's income is 20 % less than Paul income
So Quentin's income is 60 - 60×0.2 = 60-12 = 48
Sam income is 40% less than Paul income
So Sam income = 60 - 60×0.4 = 60 - 24 = 36
Now Rex give 60% income Sam
So Sam new income = 36 + 100×0.6 = 60+36 = 96
And Rex give 40% of his income to Quentin's
So Quentin's new income = 48 + 100×0.4 = 40+48 = 88
Now ratio of Quentin's new income to the Sam new income
So option (a) will be correct answer
