The table given below shows the ratio of exports and imports of a country for 5 years.

Total trade = exports + imports

Question 99

Total trade of Year 1 is twice of the total trade of Year 5. If total trade of Year 1 is 5700 crore dollars, then what is the difference (in crore dollars) in exports of Year 1 and Year 5?

Solution

Trade of year 1 = 5700

=> Exports of year 1 = $$\frac{10}{(10+9)}\times5700=3000$$

Also, trade of Year 1 is twice of the total trade of Year 5

=> Trade of year 5 = $$\frac{5700}{2}=2850$$

=> Exports of year 5 = $$\frac{12}{(12+13)}\times2850$$

= $$12\times114=1368$$

$$\therefore$$ Required difference = $$3000-1368=1632$$

=> Ans - (B)
