**Let The Salary Of The Manager And Worker Be x and y Respectively**

**So,**

**x/y = 2/3**

**x = 2y/3 -------------1**

**If Their Salaries are increased by 4000 then their new salaries = x + 4000 and y + 4000 Respectively**

**According to the given statement**

x + 4000 = 40

------------ ----

y + 4000 57

57x + 228000 = 40y + 160000

57x - 40y = 160000 - 228000

57x - 40y = - 68000 ------------2

**Substitute the value of x in equation 2**

57(2y)/3 - 40y = - 68000

(114y - 120y ) / 3 = -68000

-6y = -204000

y = -204000 / - 6

**y = 34000**

**But The New Salaries Of Workers = y + 4000**

**so new Salaries of Workers = 34000 + 4000**

** = Rs 38000**

**So The Correct Answer is A = 38000**
