Answer:

Answer 2

Answer 4 : 3

Step-by-step explanation:

Let the incomes of Jacob and Mohan are x and y respectively.

Given, Jacob and Mohan save 20% and 40% of their respective incomes.

That means, Jacob's and Mohan's expenditure are 80% and 60% of their respective incomes of x any y.

Given that their expenditures are equal.

⇒ 80% of x = 60% of y

⇒ (80/100) * x = (60/100) * y

⇒ (4/5) * x = (3/5) * y

⇒ 4y = 3x

⇒ (y/x) = (4/3)

⇒ y : x = 4 : 3
