Question:

     A man's pension on retirement from service is equal to half the average salary during last 3 years of his service. His salary from 1-1-1983 is Rs 380 per month with increment of Rs 40 due on 1-10-83, 1-10-84 and 1-10-85.  If he retires on 1-1-86, what pension does he draw per month? 

Options:
A)

     Rs 205

B)

     Rs 215

C)

     Rs 225

D)

     Rs 230

Solution:

Here first we need to calculate the average salary of last three years. 

Total Salary from 1-1-83- to 1-10-84

= 380 × 9

= Rs 3420 

Total Salary from 1-10-83 to 1-10-84 

= 420 × 12

= Rs 5040

Total Salary from 1-10-84 to 1-10-85 

= 460 × 12

= Rs 5520

Total Salary from 1-10-85 to 1-1-86 

= 500 × 3

= Rs 1500

Total salary for the period = 3420 + 5040 + 5520 + 1500 = Rs 15480

Average Salary =  1548036    = Rs 430

Pension per month =  4302    = Rs 215
