Correct Answer: 2000
Solution : Given: Before the battle, the ratio of tanks to planes in an army was 5 : 3. Let the number of tanks before battle = $5x$ and the number of planes before battle = $3x$. During the war, 1000 tanks and 800 planes were destroyed. So, the ratio becomes 2 : 1. According to the question, $\frac{(5x-1000)} {(3x-800)}=\frac{2}{1}$ ⇒ $5x-1000 = 6x-1600$ $\therefore x = 600$ So, number of tanks after war = (600 × 5) – 1000 = 2000 Hence, the correct answer is 2000.
