• B. Rs. 18.67 crores
• C. Rs. 20 crores
• D. Rs. 22.17 crores

Answer 1

The correct option is C Rs. 20 crores

Average exports of the three Companies X, Y and Z in 1993
= Rs. $[\frac{1}{3}\times (30+80+60)]$ crores $=Rs.\left(\frac{170}{3}\right)$ crores.
Average exports of the three Companies X, Y and Z in 1998
$[\frac{1}{3}\times (50+100+80)]$ crores $=Rs.\left(\frac{230}{3}\right)$
Difference $=Rs.[\left(\frac{230}{3}\right)-\left(\frac{170}{3}\right)]$ crores
= Rs.
$=Rs.\left(\frac{60}{3}\right)$ crores
= Rs. 20 crores.
