The per day salary of the worker before 2 years is Rs.200.
Present salary of the worker= Rs.264
Let the salary before 2 years be Rs.X
Salary after an year =( 110/100) * X
Salary after 2 years=( 110/100)*( 120/100)* X
So, according to the given conditions:
X *( 110/100) * ( 120/100) = 264
On solving this equation, we get X = 200
Therefore, salary before 2 years is Rs.200.
