(b)` 18.67 crores
(c)` 20 crores
(d)` 22 : 17 crores
(e)` 25 crores
Answer
Answer (as printed): C
Explanation
Average export of X, Y and Z in 2003 = $₹\frac{1}{3}(30+80+60)$ crores = $₹\frac{170}{3}$ crores. Average export of X, Y and Z in 2008 = $₹\frac{1}{3}(50+100+80)$ crores = $₹\frac{230}{3}$ crores. Required difference = $₹\frac{230}{3} - ₹\frac{170}{3}$ crores = $₹\frac{60}{3}$ crores = $₹20$ crores.
