R 50 55 70 90 65

S 45 60 20 15 25

T 60 50 55 100 110

U 24 40 60 75 120

What is the percentage increase in the export of all the countries together during the year 1999 to 2001 ? (rounded off to two digits after decimals)

A. 88.99%

B. 72.39%

C. 38.89%

D. 62.89%

Solution:

Total export of all countries together in 1999
= 40 + 25 + 55 + 60 + 50 + 40
= Rs. 270 crore
Total export of all countries together in 2001
= 45 + 50 + 90 + 15 + 100 + 75
= Rs. 375 crore

\begin{aligned} ∴ Required % increase \\ = \frac{375 - 270}{270} \times 100 \\ = \frac{105}{270} \times 100 \\ = \frac{350}{9} % \\ = 38.88 % \\ \approx 38.89 % \end{aligned}
