Correct Answer - Option 2 : 4 : 5

**Given:**

The ratio of salary of A and B = 1 : 2

The ratio of salary of A last year and current year = 5 : 6

The ratio of salary of B last year and current year = 4 : 3

**Calculation:**

Salary of A last year = 1 unit

Salary of B last year = 2 unit

Let the Salary of A last year and current year be 5x and 6x

Let the Salary of B last year and current year be 4y and 3y

Compare the salary of last year

For A

⇒ 1unit = 5x

⇒ 1/5 = x

For B

⇒ 2 unit = 4y

⇒ 1/2 = y

The ratio of salary of present year A and B = 6x : 3y

⇒ 6 × (1/5) : 3 × (1/2)

⇒ 4 : 5

**∴**** The ratio of salary of present year A and B 4 : 5 **
