• A. +25%
• B. +30%
• C. +34%
• D. +56%

Answer 1

The correct option is D

+56%

Number of educated people in 2002 = 545 million
Number of educated female in 2002
$\frac{4}{9}$ $\times$ 545 million= 242.22 million
Number of uneducated female in 2002 = 107.78 million
Number of educated male in 2002
$\frac{5}{9}$ $\times$ 545 million = 302.78 million
Number of educated male in 2003 = 378.475 million
Number of educated female in 2003 = 181.525 million
Number of uneducated female in 2003 = 168.475 million
Hence, required percentage change
$\frac{60.695}{107.78}$ $\times$ 100 = 56%
