As you can see , Increment in (19-11) i.e 8years is (29000-25000) i.e Rs4000.
That means , Increment in each year = Rs 4000/8 = Rs 500
Now, No. of years from 19th to 25th year = 6.
Total increment will be 500*6 = Rs 3000.
Salary at the time of retirement = Rs 29000 + 3000= Rs 32000.
Thus, Monthly pension = Rs (32000/2)= Rs 16000.
That means , Increment in each year = Rs 4000/8 = Rs 500
Now, No. of years from 19th to 25th year = 6.
Total increment will be 500*6 = Rs 3000.
Salary at the time of retirement = Rs 29000 + 3000= Rs 32000.
Thus, Monthly pension = Rs (32000/2)= Rs 16000.
