Explanation:

Total number of males/females in 1980 = 1000 each.

Total number males in 2000 = 180 + 205 + 160 + 100 = 645
∴ Number of dead males = 1000 – 645 = 355

Total number females in 2000 = 210 + 175 + 150 + 120 = 655
∴ Number of dead males = 1000 – 655 = 345

⇒ Ratio of dead males to females = 355 : 345 = 71 : 69.

Hence, option (d).
