Solution

Age groups
(in years)
Population Number of deaths
0 - 20 40,000 350
20 - 65 65,000 650
65 and above  15,000 x
Total  ΣP = 1,20,000 ΣD = x + 1000

CDR = 13.4

`therefore (Σ"D")/(Σ"P") xx 1000` = 13.4

`(x + 1000)/120000 xx 1000` = 13.4

x + 1000 = 13.4 x 120

x + 1000 = 1608

`therefore` x = 608
