Q4 A person purchases a television set for Rs 16000. Its life is estimated to be 20 years. If the yearly depreciation is assumed to be constant, find the rate of depreciation and the price after 8 years.
19th-11th years' salary = 2900-2500
8 years = Rs 400
So, 1 yr increament = 400/8 = Rs50
Now, 25 - 19 = 6yrs. That is, he'll retire after 6 yrs.
Therefore, after 6 yrs his salary will be:
2900 + (6*50) = 2900+ 300 = Rs 3200
Therefore, monthly pension = 3200/2 (since, its given that the pension is half of the salary)
= Rs.1600 ans.
